I am taking an online unix class and I don't have much knowledge about it. I know how to make folders and navigate them to an extent, but I need to do this:
Enter a command to see 6-letter words that begin with a "b" (uppoer or lower-case) and have an "e" as its third letter.
I have been reading and I have no idea how to do this. Please someone help.
Can someone help me with a Unix Command?
egrep '\%26lt;[Bb].e...\%26gt;' filename
the greater than and less than symbols are word anchors.
Reply:Assuming you have word list in a text file called words.txt, for example (one word per line), the following command will do that:
egrep '^[Bb].e...$' words.txt

Which is the BEST BOOK for UNIX shell Scripting? With BEST Examples and easy to Understand.?
Personally I love Unix Power Tools by O'Reilly
http://www.amazon.com/exec/obidos/ASIN/0...
Its expensive. But its also really big (1200 pages). And its full of really short little paragraphs by many many people on "this common problem, my little script to fix it"
Reply:UNIX Shell Programming
by Kochan %26amp; Wood.
This is a great book. I got more out of it than any other book that touched on the subject. And I bought a lot of books on shell scripting before I found this one.
The authours start with very easy examples that illustrate all of the critical concepts.

Is it true the Windows Vista is closer to Unix than past Windows?
I read that Windows Vista (especially the Premium edition) is closer to Unix than any other release of Windows. If it is closer to Unix, how so?
Is it true the Windows Vista is closer to Unix than past Windows?
Yeah that is true.
Reply:Not true!
Reply:No, that is not true. Vista and Unix systems have got nothing technical in common.
Maybe the article just compared some key features of the operating system like user management or security related functions. In that case vista is maybe a little bit closer to UNIX as other windows releases are but still not comparable. Vista and UNIX based system have radical different approaches to achieve their functionality.
But in essence, UNIX and windows based operating systems have nothing in common except that they are both state of the art software products which help you to use your hardware.

How to make zip file of any file in UNIX OS operated LAN system.?
Since, the file size is too large i.e. in GB, i want to make zip file of this big file. My file is in UNIX OS operated LAN system. Also, if i want to make two file from this one big file in UNIX,is it possible? if yes what should i do?
How to make zip file of any file in UNIX OS operated LAN system.?
Unix uses tar and gzip mostly, but the zip command might be there. Type
zip zipfilename.zip filenametozip
Use zipsplit to split the zip file.
Otherwise,
tar cvfz file.tar.gz /path/to/file/to/compress

Fundamental differences between Windows, Mac OS, UNIX, and Linux operating systems for personal computers?
What are the differences between Windows, Mac OS, UNIX, and Linux operating systems for personal computers. What are the unique characteristics of mainframe operating systems.?
Fundamental differences between Windows, Mac OS, UNIX, and Linux operating systems for personal computers?
Windows is a general applications OS, targeted largely at businesses. It has a very wide range of applications, many of which can be downloaded and run for free. It is notorious for the number of security holes it has, and has amazingly bad tech support.
MacOS is the operating system for Apple computers. It has a highly polished user interface, takes very little effort to use, and has decent tech support. Unfortunately, it isn't as popular as Windows, so you won't find the bredth of applications available for it. Also, if you want to do something cool, special and different, then you're hozed because the OS is designed around people who don't want to customize. MacOS really only runs on Apple computers, and the whole package tends to be more expensive than the Windows equivalent for the same power, although proponents aruge that the maintenance effort in Windows makes up for it.
Unix is a family of operating systems designed to run in a mainframe environment. There have been some efforts to make Unix work on PC's, but for the most part it remains the domain of large business systems. It has numerous user interfaces which tend to range from user hostile to badly outdated, but it works very, very effectively for server applications.
Linux is the most popular attempt to create a Unix-like operating system for personal computers. Until recently, Linux also had all of the limitations of Unix, with the sole benefit that you could run it on an Intel based PC. This one benefit has created an environment where pretty much anybody can write software for it, and they have. There's an amazing plethora of applications available for Linux. Unfortunately, they have traditionally been difficult to install, and not written by someone who had the user interface in mind. On the good side, both the operating system and most of the applications for it are entirely free.
Ubuntu has improved significantly on the "difficult to use" factor of Linux systems, but that is a story for another question.
The primary unique characteristic of mainframes is that they are multi-component systems, and each component tended to have its own processor. This differs from a desktop system because in that environment a single processor does all the thinking for most of the rest of the parts. This differentiation has been blurred recently, as desktop peripherals like video cards and storage devices have increased their intelligence in an effort to speed up their functionality and take load off of the main processor.
Reply:Windows: Got its start with IBM Personal Computer in the 1980s and that alone caused businesses to focus on it. I can't see anything about Windows that indicates it is targeted at businesses. It just so happens that many small to medium sized businesses like the Microsoft Office software which makes them think Microsoft for the operating system as well. There are two main advantages to Windows: 1. Most companies only train their technical staff in troubleshooting Windows. 2. Almost all games have Windows compatibility even though an increasing number have Mac and Linux compatibility.
Mac OS: Based on Berkeley (University of Cal at Berkeley) Software Division version of UNIX and centered on the kernel developed at Carnegie Mellon University. It is the fastest growing operating system (6.7% market share as of September 2007). From the introduction of the mouse and windows (lower case w) to the latest version, the Mac has set the pace for all other home computer systems. Advantages are ease of use, fully integrated hardware configurations thus avoiding conflicts and pre-installed applications that 'just work', no-brainer printer and peripheral hardware setup, second-largest software selection, tremendous power and high security.
Linux: Based very roughly on UNIX, it has a small and diminishing following (less than 1 percent market share) and the fewest ready-to-run software titles. The technically-challenged public has little interest in the complexity of partitioning and software tweaking that is often necessary to make it work and keep the computer up and running. Advantage: Lower initial cost and image of the underdog.
Mainframe systems: The computer hardware tends to be rigidly configured since they are intended to produce some specific results. Most modern systems are based on UNIX, particularly in government and military because of the tremendous power, versatility and security. The IBM mainframes can use a variety of operating systems, even Linux, but the most popular is z-OS which is UNIX with a multitude of advanced logging systems, security enhancements and Network File System improvements.

In UNIX, how do you determine which of the commands (ie: cd, pwd, ls, cat) are external?
I was asked this in a UNIX course and don't have any clue. Can anyone explain it?
In UNIX, how do you determine which of the commands (ie: cd, pwd, ls, cat) are external?
man (insert name of shell here) to see the list of builtins for the shell you are using, e.g.:
man zsh
man bash
You can also use the type command:
$ type pwd
pwd is a shell builtin
$ type ethtool
ethtool is /usr/sbin/ethtool

Can you help me with a "UNIX for Dummies" type question regarding a RegExp query?
All I want to do is search for an EXACT PHRASE in zipped files in a UNIX database, and have the querry return all instances of the exact phrase. (UNIX instruction manuals are too confusing!)
So, if I wanted to search a bunch of zipped files in a UNIX database for files containing the phrase
"the more details you provide", case insensitive - what exactly would I enter? I've used the GREP commands before, but don't really know what I'm doing. I'll really appreciate your help!
Can you help me with a "UNIX for Dummies" type question regarding a RegExp query?
What you are asking for, regex searching in blobs is tough enough, but to add the fact that the files in the blobs are zipped really adds a wrench into the mix.
Ideally, you might index the files before they are zipped. Then though an olap cube you could wrench the data out that you need. If this isn't feasable, then the solution depends on your database. For example, in oracle, you can use java to extract the files, unzip to memory, then run regex queries on each file. Expect your queries to be mighty slow and processor intensive.
Worst case scenario you select a single blob at a time, unzip it, run grep -e or other regex utility on it, store the results, then move on to the next file. Something like this will take quite a while to run.
My suggestion is to work out a way to index the files based on what you think the regex expressions would be. Then run your queries against the indexed data for quick results.
I'm going to hate myself for saying this, but check out Kimball's book on data wharehousing. A bit more info than you'll need, but it'll provide a decent start for you.
Reply:Firstly if they're zipped up and stored in the database you're out of luck because you're going to have to extract all of them, unzip them and then search them.
Assuming that you infact actually have big blob columns with unzipped data files in them, you don't need regex for an exact match, try:
SELECT something FROM table WHERE column LIKE '%he more details you provide%';
Good luck.
Reply:Here is what you need to do:
1. Simple example: Assume that you need to search for "the more details you provide" in a file a.zip. Run the command:
# zcat -n a.zip | grep -i "the more details you provide"
Here is the explaination of this command: zcat will cat the file even if its zipped. The grep will try to find out the text string from this file. The "-i" switch to grep command will enable "ignore case" nature of grep.
2. So if you know the list of files, you can do something like this:
# export FILELIST="a.zip b.zip c.zip d.zip"
# for file in FILELIST; do zcat -n $file | sed "s/^/$file: /" | grep -i "the more details you provide"; done
Do let me know if you face any issues.

Is Unix a prerequisite for learning Oracle RDBMS?
I do not know Unix Operating System. Now, I need to learn Oracle RDBMS.
Is Unix a prerequisite for learning Oracle RDBMS?
Theoritically No, Practically yes.
You are going in for Oracle RDBMS i think for better job prospects, although not from being UNIX background is in no way a hindrance to learn oracle.
but for better job prospects, it is advisable that you learn Unix also side by side as Unix with Oracle has far more demand in market than just Oracle on windows.
I think everyone working on databases will agree on this :)
Reply:No. uracle runs on unix and windows. so get the verstion you want.
i used oracle for many years but on windows flat form.

Reply:Unix is not a prerequisite for learning Oracle RDBMS.
You can use Windows OS with Oracle RDBMS. Here you can get Oracle knowledge but not able to use the OS functionalities more effectively. In unix, you can write an effective shell script for oracle,schedule a script in crontab, able to set environment variables for multiple databases by running a single shell script, switch between diff users, and lots of things are there. If you want to learn Oracle along with OS, start using unix OS with Oracle RDBMS.

In UNIX, what command could join two content from different file together, without any duplication?
for example, i have two file:
file A: 1,2,3,4,5,6
file B: 5,6,7,8,9,10
if i want to join the together and become file C, without any duplication, like:
file C: 1,2,3,4,5,6,7,8,9,10
what UNIX command should I use to combin two files together without any data duplication.
Thank you very much, everybody.
In UNIX, what command could join two content from different file together, without any duplication?
If the values are each on their own line, then:
cat A B | sort -n | uniq %26gt; C
If the text you have is not numbers, don't specify "-n" on sort.
If you want to know how many instances of each number was in the file, then
cat A B | sort -n | uniq -c %26gt; C
(uniq -c does a "count" of values but only prints each unique value once).
If the files contain lists of numbers separated by commas (as your example shows) then you could try:
cat A B | sed -e 's/,/\n/g' | sort -n | uniq %26gt; C
But if you want all of the results to end up back into a single line, again like your example shows, then:
cat A B | sed -e 's/,/\n/g' | sort -n | uniq | sed -e 'N s/\n/,/g' %26gt; C
Alternatively you could do all of this with a single Perl script...

Learning Unix?
I learnt from experiences, but I suppose you could more than likely use a book. Make sure to act with a UNIX-based system every day for best effect though.
Reply:It all depends what OS, you are using. Unix is very big. I personally have been using Ubuntu Linux for half a year now, and have only bought one book for useful commands. Linux's power is in its community, which really wants to help you like yahoo answers.
Ideally, no. You don't need coaching if you have BRAINS.
Reply:I would say that its easy to learn.
Online sources can quickly get you into the basic commands to move around and do things.
The "man" command is the built-in help files. Doing a "man -k mail" would show you all of the commands on the machine that have something to do with mail, then doing just a man on one of those will bring up the help file on that command.
Much of unix is raw code so you can even view the files to see how they do things.
Unix has been around for longer than windows. Even longer than internet (basically). So there is alot of online stuff to help you and many forums that you can ask a specific question.
Altho, I would have to say that Linux is probably easier to learn (for all the same reasons) even tho it does more. But Unix is the powerhouse.

The "man" command is the built-in help files. Doing a "man -k mail" would show you all of the commands on the machine that have something to do with mail, then doing just a man on one of those will bring up the help file on that command.
Much of unix is raw code so you can even view the files to see how they do things.
Unix has been around for longer than windows. Even longer than internet (basically). So there is alot of online stuff to help you and many forums that you can ask a specific question.
Altho, I would have to say that Linux is probably easier to learn (for all the same reasons) even tho it does more. But Unix is the powerhouse.

Is Mac OS X based on Unix?
Somebody told me that the Mac OSX is developed based on UNIX. I have been working with Mac for many years but this is the first time I heard that OSX is based on UNIX platform or is designed on UNIX coding or something like that. Could someone give me a detailed answer?
Is Mac OS X based on Unix?
Yes. And not just "based on". It IS a unix flavour, called "Free BSD".
To one of the answerers above - all the mordern unix systems (OS/X included) have GUI, but it is not a part of OS.
Reply:Mac OS X ISN'T FreeBSD. FreeBSD is another OS altogether. While OS X has some FreeBSD code, it is certainly different. The kernels are completely different, as OS X uses a Mach-based kernel (XNU). OS X design-wise and code-wise overall is most similar to its direct predecessor, the NEXTSTEP OS. Report It
Reply:Sort of.
The underlying system is based on FreeBSD which was a re-write of
BSD with open source software. BSD was an evolution of the UNIX
from the 70s.
Note, however, that NONE of the code from the original UNIX exists
in FreeBSD because software developers developed their own versions.
Most of the new stuff is provided under the GNU license (open source).
Linux also uses a great deal of software developed under the GNU
license, but the kernel is different.

Practise Unix?
Is there any source where I can practise Unix?
Practise Unix?
There are compiled unix commands that will work on Windows (Im guessing that is what you have). The UnxUtils are a good set.
You might also want to ask your ISP (the providor that puts you on the internet) and see if they offer shell accounts. Some do. Then you would be able to login to a unix or linux machine that they run and play with the commands there.
Reply:http://cyberspace.org/ offers free accounts...
Reply:Good question, you will need to install Linux to your computer to get the source. You can make your computer dual boots system to accomplish this.

Installing Unix Programs on Mac OS X?
If I want to install a unix program so that when I type in the command in the terminal, the program runs, in which directory should the file be saved? I am running version 10.4
Installing Unix Programs on Mac OS X?
Unless the program has been built in such a way that it expects to be in a certain place, it doesn't matter.
Put it anywhere.
If you don't want to type an explicit path to it each time, then put it in one of the directories in your $PATH. Type echo $PATH to find out what they are.
Reply:Normally user installed programs are installed in /usr/bin or usr/local/bin directory. Those paths are usually in your $PATH variable.
But, you can really install it anywhere you want to, including a USB drive or removable storage. You simply add the full path of the install directory to your $PATH invironment variable and export it. That way, all you have to do is type the name of the executable.

In UNIX, what command could join two content from different file together, without any duplication?
for example, i have two file:
file A: 1,2,3,4,5,6
file B: 5,6,7,8,9,10
if i want to join the together and become file C, without any duplication, like:
file C: 1,2,3,4,5,6,7,8,9,10
what UNIX command should I use to combin two files together without any data duplication.
Thank you very much, everybody.
In UNIX, what command could join two content from different file together, without any duplication?
If the values are each on their own line, then:
cat A B | sort -n | uniq %26gt; C
If the text you have is not numbers, don't specify "-n" on sort.
If you want to know how many instances of each number was in the file, then
cat A B | sort -n | uniq -c %26gt; C
(uniq -c does a "count" of values but only prints each unique value once).
If the files contain lists of numbers separated by commas (as your example shows) then you could try:
cat A B | sed -e 's/,/\n/g' | sort -n | uniq %26gt; C
But if you want all of the results to end up back into a single line, again like your example shows, then:
cat A B | sed -e 's/,/\n/g' | sort -n | uniq | sed -e 'N s/\n/,/g' %26gt; C
Alternatively you could do all of this with a single Perl script...

Linux / Unix Question?
In UNIX systems, two critical files located under the etc directory store user account information . Explain the the differences between the /etc/passwd and the /etc/shadow files as they relate to user information confidentiality.
Linux / Unix Question?
/etc/passwd files store information differently than /etc/shadow files. In the passwd file, the actual password is stored there; when shadowing is used, a "x" is placed in the file, and the shadow file serves as an encrytped hash file to look up the password. Basically, when password shadowing is used, it makes it a lot more secure, because the passwords aren't just easily looked up in a file.

what software that i can to download to run in intell processor as a free software to learn unix.
Learning unix?
I'd say download a free version of linux. it should have enough for you to learn the basic unix commands and allow you to learn shell scripting along with using things like awk, grep and sed. after that if you want you can invest money into getting a professional copy of either red hat or SuSe linux and try learning about administration.
O'Reilley had a couple of really good books on UNIX systems administration and Network administration. The good thing about UNIX/LINUX there is no end to how much you can grow. also compared to windows its relatively cheaper to learn UNIX since most of the software come packaged with the OS and you won't have to spend money on software. For example: Suse linux comes with a copy of Star Office (very similar to MS Office) it also comes with a C++ compiler and a plethora of other languages. Enjoy

Why should I get Linux/Unix if I'm into hacking?
I'm a budding hacker and I'm teaching myself to code, networking, ports, protocols, etc and I was wondering why people always talk about Linux/Unix being a great OS for hacking.
P.S. - Does anyone know of any GOOD books, websites, billboards, etc. (kidding about the billboard) that teach about hacking or about how computers work?
Why should I get Linux/Unix if I'm into hacking?
Linux is a great system for programmers etc. because it's strength lies in it's command line power, not so much in the GUI. Many popular exploit/hack tools are for linux, and are much more difficult in windows, or simply do not work at all or are not made for windows. hope this helps.

Select the photos, right-click on them (or ctrl-click if you have a single-button mouse) and select "Open with" from the menu. Then select "Preview", if it's in the list. If it's not in the list, select "Other" and navigate to the Preview application (it's at /Applications/Preview). If Preview is greyed out, make sure to choose "Enable: All Applications" instead of "Enable: Recommended Applications" in the pull down menu.
Optionally, you can check the "Always Open With" check box.

Unix beginner...?
i'm very interested in UNIX, but i know almost nothing about it...
How do I start learning...
Unix beginner...?
Take an old PC. Clean out the disks.
Wait!
Before you do that, download the ISO images from http://www.freebsd.org/where.html. Do yourself a favor and get the latest (6.2 as I write this answer). Create CD's from the ISO images. The first CD should be bootable.
Read the INSTALL and README and other documentation files on the first CD. Yes, really, read them.
Then boot your computer from the first disk and *READ* and follow the directions. THIS WILL WIPE OUT THE WINDOWS OS ON YOUR COMPUTER.
Be conservative about installing packages.
Do install the ports directory on your disk if you have the space.
Do install the source tree on you disk if you have the space.
Do have the space.
Log on as root, cd to /usr/share/doc/en and read the handbook, also available at http://www.freebsd.org/doc/en_US.ISO8859...
From there, you're on your own.
Now, that's just FreeBSD.
Once you understand it, then you can check out http://www.rpath.com for another flavor or Unix.
The great thing about Unix is that there are so many to choose from.
Reply:Also, I don't mean to be insulting if you already know this but, you should be sure you really want to learn Unix and not Linux. Unix is more rare outside of data-centers and larger enterprises. Linux is very common for developers and smaller websites. They are increasingly different the deeper you get into them but on the surface appear very similar.
Reply:Get and old computer and install the OS. It sounds simple but you never really learn except for hands on.
Sun Micro is now giving Solaris 10 away. It is a true Unix OS.
Go to your local computer (used) store and ask if they have any old SPARC computers. If not a P-III 500mhz with 512mb of RAM will do.
Here is the link to the OS.

The best way to learn is get on the system and start doing things. Learn how to use either emacs or vi editor also.

Log on as root, cd to /usr/share/doc/en and read the handbook, also available at http://www.freebsd.org/doc/en_US.ISO8859...
From there, you're on your own.
Now, that's just FreeBSD.
Once you understand it, then you can check out http://www.rpath.com for another flavor or Unix.
The great thing about Unix is that there are so many to choose from.
Reply:Also, I don't mean to be insulting if you already know this but, you should be sure you really want to learn Unix and not Linux. Unix is more rare outside of data-centers and larger enterprises. Linux is very common for developers and smaller websites. They are increasingly different the deeper you get into them but on the surface appear very similar.
Reply:Get and old computer and install the OS. It sounds simple but you never really learn except for hands on.
Sun Micro is now giving Solaris 10 away. It is a true Unix OS.
Go to your local computer (used) store and ask if they have any old SPARC computers. If not a P-III 500mhz with 512mb of RAM will do.
Here is the link to the OS.
For PC computer http://www.sun.com/software/solaris/get....

The best way to learn is get on the system and start doing things. Learn how to use either emacs or vi editor also.
Is it possible to run Linux or Unix and Vista on my computer without partitioning the hard drive?
Running Linux or Unix from within Vista would be ideal, but I realise this is probably not possible because they are separate OSs. I've just started a course in IT and they've told me to put Unix, or failing that Linux on my computer, but I don't want to partition my hard drive because it wipes it and I want all my programs and data in one place, plus it seems like a lot of hassle I can't be arsed with. They've also told me about Cigywn but I've had a look and it looks too different from Linux/Unix to be useful. So if there's any possible chance I'm able to run Linux/Unix without partitioning my hard drive please let me know...
Is it possible to run Linux or Unix and Vista on my computer without partitioning the hard drive?
One option not mentioned so far and for me the easiest is similar to the option of an external drive. Install a second hard drive, it only needs to be a smallish one 20gig or above would be adequate. Install your Linux onto this and it is then completely independent of your Windows drive. Try the Micro Mart forum at www.micromart.co.uk where I am sure some of the guys will help you. You have to join up but it's completely free and they have some Linux wizards there. Hope this helps.
Reply:It is possible though - just use VMWare, or any other Virtual Machine software.
Additionally, partitioning your disk drive doesn't wipe out all your old data and programs. Just re-size your current partition using software like QParted -
http://qtparted.sourceforge.net/index.en...
On top of that, you can also run Linux as a LiveCD - no need to install anything.
Wow! Open Source and Free software fives you such choice, doesn't it? Welcome to freedom :)
Reply:yes you can and both ways are mentioned above either using virtual machine. or d/ling a live cd. most of the linux distros can be d/led as live cds which can be ran directly from the cdrom.
Reply:No, you MUST partition your hard drive to run both.
Reply:Seconding VMWare. That's what I use at work. Let's you easily switch between Linux and Windows, something you'll want to do a lot as a student.
Live CD would be my second choice.
You can also try to find a copy of a software called Partition Magic that lets you dynamically resize partition with wiping it. Then you could go for multiboot.
I prefer VMWare, although you need about 2x the amount of RAM you would otherwise.
Reply:liveCD is one possibility.
I would try installing it to an external drive. You would either have to install grub (and may have problems if the external drive were not plugged in - I am not sure), or come up with another boot option. You could always restore the MBR if you had grub problems.
Reply:You can only run an OS within an OS with a virtual machine. Unless you use Putty or something.
Reply:Running Linux in "emulation" is slowwwwwwww
and is no good for a speed freak like me!
Running Linux from the CD/DVD is equally slow because of the seek time.
I agree with the separate hard drive option to put Linux onto.
Just change the boot drive in the BIOS to the OS you want.
PS
Yes I have tried them too!
Reply:i don't know if Vista will work with this solution, but for xp it works:
http://wubi-installer.org/
it installs linux into a virtual disk file within your existing partition...
Good Luck!
Reply:Of course! Just add another hard drive!
Sorry, but this is the only way. It isn't that hard, though. Just buy another hard drive (or salvage an old one), pop it in, boot to a Unix/Linux distro installation CD, and overwrite the new hard drive's partitions.
You will have to keep your Vista hard drive as master because Vista sucks that way. As a result, you will have to make one tinsy little ajustment to the Master Boot Record on your Vista hard drive (you modify the mount point). Honestly, I do not know how to do this on distros other than OpenSUSE 10.2, but it should be self explanatory.
I hope this answers your question.
Reply:Linux offers a version that operates as a bootable disk. It is not installed on the hard drive.
Maybe you could consider adding a separate hard drive to run Linux or Unix on. These are even available as external drives.

Like Petwanel says, and I think the disk can be downloaded from the Linux pages for free and burned to your own CD.
Reply:Virtual Machine free from Microsoft could be an answer but here is what I have done.
I have a SATA drive with SUSe 10.2 on fully loaded, I've even got my scanner working.
I then have a IDE drive which plugs into a drive bay.
Now for reasons known to some when I plug the the Ide drive in the bay and switch on, that drive takes over the booting and on that drive I have XP. without that drive it boots from SUSe.
Best of both worlds eh.
Reply:Yes. You need a Linux Distro in the form of A Live CD or Live DVD. The book Linux for Dummies All In One Desk Reference is one source that has the Live CD.
Reply:The best way I have found is to download vmware player which is free. You could then download any of the 100s of virtual appliances which include many different linux and unix distros. This way you could run many different linux distros at the same time from Vista without having to go through the linux installation process. These will run at near native speed, but you may have some problems viewing video or listening to audio from linux.
Reply:It is possible to install Linux/Unix on Vista without partitioning the hard drive.
Just install Microsoft's Virtual PC 2007 and install it through there.
Your base system will be Vista. Every time you want use Linux, Vista has to be running.

QA testing in Unix environment?
I wanna know what commands are mostly used when we do QA testing in Unix environment. and tell me how to execute batch preocesses in Unix.
QA testing in Unix environment?
This question is vague.Unix commands would really depend on what task your are performing
some of the unix commands which i use are
1.ls
2.scp-to cpy the build from one machine to the other machine
3.grep- to find the patterns of files or contents of the files
4.cp- to cpy a file
5.mv- to rename a file
6.vi commands - to update the files
3.cat -to creat or view files
7.ps -ef |grep pID- to get process name
9.kill -9 pID - to kill a process
10.find- to find files
11.alias- to create shorcuts for paths
You might check this link
http://creativebrother.freehosting.net/q...
As to batch processes its much the same as any other system. Create a batch file (unix shell script file) with all of the commands in it and run it. Or automate it into the AT system (on unix its called cron)

Unix or Linux ?
Learn to work with Linux. It's easily available, easy to install, widely used, and provides a good base for learning *nix systems. 80pct of what you learn on Linux will apply directly to Unix, and the other 20pct will be minor variations from Linux to Unix.. or Linux (A) to Linux (B)... or to FreeBSD or Solaris or AIX or...
Just be sure to start with a fairly vanilla distribution like Ubuntu, Slackware, or Debian: no funky, x86-64 optimized to run off a cd and store persistent changes on a USB stick using a new package system and running the whole OS from under 100MB of RAM- style distribution, ok?
Reply:Unix presents some unique issues -- there are over 50 variations of the OS and not all are compatible. Linux on the other hand is making some inroads into WinTel and you will find that the demand for programming skills in this OS is growing. You want to give yourself the opportunity to work in the growing environment and I'd suggest Linux first.
Reply:linux is based off unix. linux is the more popular of the 2, unix is less hacked as windows has most hacks. your young u say so learn it all u have time...
Reply:UNIX is better.
Reply:Ubuntu Linux is the easiest and it's free. www.ubuntu.com
Reply:Instead of thinking of it as Unix or Linux try thinking of it as *nix. Much of the code is going to portable between both systems with little or no modification so instead of focusing on the platform how about just focusing on writing efficient, secure code.
Keep in mind that most organizations are Microsoft shops so that is the majority of the jobs in the market. It's good that you are trying to understand multiple platforms but don't let those Microsoft skills degrade too much.
Reply:if u did work so much in unix u should now it's more secure and advanced.... both are good for learning programming, pretty same commands

Unix vs microsoft?
If we have CD-ROM, DVD-ROM, floppy drive and TWENTY-FOUR (24) logic disk partitions on a single Windows system with a very big disk drive, how do we handle these drives per Microsoft's 26-letter drive naming convention? If it is on a Unix or Linux system, do we have similar problem
Unix vs microsoft?
As long as you are using NTFS in Windows 2000/XP or greater, then you can map the partitions as directories under an existing drive letter (typically C:). Otherwise, you are limited to 26... A/B for floppy, C for the boot partition, then usually D/E for CD/DVD, and 21 more for additional partitions.
Essentially, UNIX requires you to "mount" all partitions (and external devices) as a directories within the root, or slash / (which represent the boot partition)... so UNIX/Linux has never had a limitation.
The final question is why 24 partitions? The latest Windows and Unix/Linux versions can handle Terabyte drives without the need for partitioning.
Reply:Why so many partitions? Totally illogical.
Reply:I think in windows it would then go aa:\ ab:\ and so on, but I don't know how many drives you could have total. in unix(linux, at least) the cd and dvd wouldn't matter because they would be cd0, dvd0 or something like that. the partitions would be sda1 - sda99 or hda1 - hda99. I don't know how many it would support total either. but if you have a disk big enough to need all those partitions, you should get lots of disks or a raid in case that one disk goes out.

Unix Directory listing?
is there a command in Unix (something like ls -"X") to list the directories and all subdirectories.
While ls -d does this, i want the full roots of the folder.
I cannot find a way to do this.
my intended result would look like this...
/home/toodles/dir1
/home/toodles/dir2
/home/toodles/dir2/subdir
Thanks in advance,
Unix Directory listing?
You could do:
find [directory] -type d -print
As long as you list the full path for [directory], it will be shown on each individual entry.
Example:
# find /home/oracle -type d -print
/home/oracle
/home/oracle/.kde
/home/oracle/.kde/Autostart
/home/oracle/scratch
/home/oracle/bin
This prints the top-level directory as well (/home/oracle in this case). If you want to skip that, add "-mindepth 1" to the arguments:
find [directory] -mindepth 1 -type d -print

Unix program.?
You know when you type in "bash" it makes the Unix program so much easier to use. I was wondering is there a way to do that while writing a program? Im sick and tired of switching back and forth between edit mode and write mode.
Unix program.?
are you using vi? i think it has a 'visual' mode that's much more usable, it works the way every other editor in the world works.
vi is weird! but i've gotten used to it..
some like emacs, you might try that as well.
Reply:When you type in "bash" you are just starting a bash shell. Presumably you are already in some older or less powerful shell.
When you speak of edit/write mode are you talking about vi? If so, just use some other editor. There are several widely available for unix and many more for linux e.g. gedit, kedit, kate, etc., off the top of my head.

Unix Help???
How do you determine a device name when using unix?
I'm trying to extract some files with the command
cpio -idmv%26lt;/dev/ ???
But I don't know the device name. The drive (exabyte exb-8500) is an optical drive (like a cd rom) connected to
scsi scusi card.I'm trying to extract from a 8mm tapes.
When I use the command (Which works with my dds-4 tapes
using a diffrent machine-hp,dat40) cpio -idmv %26lt;/dev/nst0 the machine just freezes. Is it because i need the device name?
please help..how do I get the device name? how Do I even set permissions to that device if I can't see it?

Unix Administrator - What do they do?"?
Can anyone explain to me what a unix administrator does in non technical terms?!?!?
Thanks
Unix Administrator - What do they do?"?
Exactly the same as Windows administrators, but on Unix machines. Setting up machines, controlling users and security, maintaining networks, recovering from user errors and trying to keep everyone happy. Quite a lot of them live in super luxury house or apartments, these are generally the best at their job, and are often unrecognisable as Unix admins. This last rule also applies to Windows and Linux administrators.
Reply:I bet there is a lot of people who are wondering that. A lot of UNIX (and Solaris=more obscure form of Unix) admins hate Windows. They hate not only Microsoft Windows but any operating systems that allows a person to accomplish a task with few mouse clicks. These Unix admins prefare to work on a command line. As another poster pointed out, Unix admins are known for their reclusiveness.
Reply:Unix is an old operating system. Its built for the days when there were not any PCs (personal computers) and everyone connected their keyboard and monitor to one big computer. Everyone had to have an account.
The adminisitrator managed the system. The accounts, kept the programs running, made sure that the users didnt messup the server or mess with each other. Think of it as the principle in a school.
Now Linux, Mac, Windows all have administrators but since its often a computer with only one user it doesnt really have the function of the old unix admins.
Reply:Most of them are dungeon masters... some of them live in their parent's basements. They tell obscure jokes, and sometimes grow beards.

UNIX codes?
can you tell me how to find ip address in linux and unix. and also chat between computers using them.
UNIX codes?
ip address? if you know the hostname use "nslookup hostname.com"
if they are connecting to you, or attempting to do so, check your "netstat" output
if you want to chat in between computers, you can use 'ytalk' if it is installed. I dont think "ytalkd" is installed by default anymore. if you are both running local smtps you can just:
"echo "your message here" | mail root@ipaddress"
UNIX codes?
ip address? if you know the hostname use "nslookup hostname.com"
if they are connecting to you, or attempting to do so, check your "netstat" output
if you want to chat in between computers, you can use 'ytalk' if it is installed. I dont think "ytalkd" is installed by default anymore. if you are both running local smtps you can just:
"echo "your message here" | mail root@ipaddress"
Unix/Linux doit program?
What commands would I need to write a program 'doit' that takes another Unix/Linux command as an argument and executes that command. For example executing
doit cat /etc/motd
would invoke the cat command on the file /etc/motd which will print the current "message of the day".
Any help appreciated!
Unix/Linux doit program?
Most shell interpreters don't *need* a 'doit' program - just saying 'cat /etc/motd' is sufficient But if you feel the need to do it the hard way (at the expense of a few extra fork/exec pairs you'd not have done the easy way), this should work:
/bin/sh -c "/bin/cat /etc/motd"
doit cat /etc/motd
would invoke the cat command on the file /etc/motd which will print the current "message of the day".

Sort or search unix file by using tab as delimiter?
have a unix file with the following format:
one\TABtwo three\TABI love NBA\N
world\TABfour five\TABI love NFL\N
How can I search the second column using grep, or sort them by the second column? I couldn't type tab in cygwin or unix shell.
Sort or search unix file by using tab as delimiter?
In Unix, under the Bash shell, you can type in the tab character by using: Ctrl+V, TAB
e.g. you can use grep as follows:
grep "%26lt;ctrl+v,tab%26gt;two" myfile.txt
You can try cut as follows:
cut -f2 -d"ctrl+v,tab" myfile.txt
which will return the entire second column.
You can also use awk...
Reply:Typically awk is good for filtering column-based output - e.g.:
awk '$4 == 1 { print }'
will print all lines where the 4th colums is equal to 1.
and:
awk 'BEGIN { total = 0 } { total += $5; print $5 } END { print "total: ", total }'
will print the sum of all the numbers in column 5.
awk already understands that tabs or sequences of spaces delimit columns.
The Unix sort utility also understands columns as such and will deal fine with tabs.
sort -k2n foo
will sort the file foo based on the numerical value of column 2.
If you need to type a tab in the shell, typically you hit Ctrl+V first and then type the tab and that should get you a tab character. You would need to enclose that tab in quotes in the command-line as well.

Unix command?
hi,
I wd like to know unix command with that we can see year of creation of any file. kindly help mr to know which command we hv in solaris for the same.
if we have to wrte shell script for the same then i need a code for the same.
Unix command?
Use the "ls -ltr" command.
-l option shows the modification time of a file.
-t option presents the files in the order of their modification
-r options sorts the above listing.
you can also use the "find" command...
Reply:Use the "ls -ltr" command.
Reply:try this www. unix basic commands.com
%26amp;mandrakelinux
Reply:One thing other answers might have missed is that you're asking for the year the files were created. I'm not aware of any contemporary *nix filesystems which store this information. Typically, all that is stored is the date the file was last modified, the date it was last accessed, and the date the file's inode(s) was/were last changed.
If you just want to see the date the file was last modified, try "ls --full-time". That works under GNU ls - not sure if Solaris uses GNU ls or not, but it's worth a try.

Unix vs Linux: what are they and how to install for free?
How would I install Unix and Linux on my Windows Vista laptop for free and without messing up anything.
I am very new at this, are both easy to use, learn and what are they for?
Many thanks
Unix vs Linux: what are they and how to install for free?
Look at one of www.openbsd.org or www.netbsd.org or www.freebsd.org or www.opensolaris.org. At this time, for you, being a new comer to Unix/Linux, I suggest you use only Linux until you get used to it. Unices are a bit difficult to install and use and their user and support community is small and focussed. The above mentioned ones are some of freely available UNIX variants. Look at www.distrowatch.com for more such.
Use Ubuntu or Debian. I suggest you go for Debian. It does take a lot of work to install Debian as opposed to Ubuntu. But after installing, Ubuntu takes a lot of work to get it to your tastes while Debian takes almost no work to come to your tastes.
For Unix as well as Linux, this quote is true. "Unix is user friendly. It chooses its friends.". Both are operating systems. They are for doing things that you want done using your computer. Much the same as Windows. They differ by being a tad cleverer than Windows.
I suggest you go to www.debian.org and look at the installation manual. In short steps, this is what you have to do to install Debian successfully. Download Debian CD1. Delete a partition. Brun the CD1 to a CD. Boot your laptop with the CD1. Ask the installer to use the empty space that you created by deleting a partition from Windows. Answer a few network related questions such as domain name, DNS, IP address and such. Let it install the CD1 for a laptop configuration. Pop the CD out when the installation is over and reboot into the Linux system.
After you boot into the Linux system, open System%26gt;Administration%26gt;Synaptic and install xchat. With xchat, join #debian on irc.freenode.net to start asking questions and getting answers live.
Also join some of the many Debian user mailing lists.
Reply:First off, Unix and Linux are like Polar bears and Grizzly bears. They are related, but fundamentally different from each other.
There are loads of Unix variants out there, just like there are loads of Linux variants out there. Picking one can be a huge chore.
For a beginner to Free and Open Source software, I'd recommend starting off with Ubuntu. It's popular, easy to get help, easy to get started, and coexists well with Windows.
You can download the Ubuntu 7.10 CD, burn it to CD, and boot your PC from it. You will get a LiveCD version of Ubuntu Linux to use. If you like it, you can double-click on the INSTALL icon to put it on your HD.
If you do decide to install onto your HD, make sure you choose the FREE SPACE option! Otherwise it will erase your Vista installation as well. Aside from that, you shouldn't have any problems.
Reply:Unix and Linux are operating system like Microsoft Windows only it is free and will either replace Vista or configure your computer to "Dual boot"
Unix has been around for many years and was developed by universities (Which is why it is free). It is highly stable however extremely user violent. Its interface consists of a text type command set similar to that used by MSDOS (It actually preceeds MSDOS by many years).
Linux was developed on top of the Unix foundation by a man called Linus. Thus the name Linus + Unix = Linux. This operating system was developed to make life a little easier for the developers of Unix platforms. It contains a better subset of API (Advanced Programming Interfaces) and it is ALOT easier to use.
This said Linux could still be considered user violent to those inexperienced with how a computer functions and could be frustrating for anybody wanting to use their computer to play games. Linux DOES HAVE GAMES but it cannot play those developed for the windows platform unless run through some sort of emulation program like WINE.
These operating systems are great. they are older and faster smaller (at the core) and more stable then windows and can really unlock the potential of your computer.
I reitterate though that they are not easy to use and if you are unsure about these things you should not install them...
On a side note for windows operating systems Id advise you DOWNGRADE to Windows XP. It is a far superior operating system then the latest Vista platform. Its smaller, faster and just as easy to use. Microsoft screwed up big time on Vista they just refuse to admit it.

can anybody tell me where to learn UNIX in Hyderabad which teaches in 1 or two days ?
Unix Operating System?
Never heard of Hyderabad. Unix/Linux is easy. I'm using SuSE Linux by Novell software to send this message. Unix branched off into BSD Unix and many many Linux distributions. Since most are free, just download one! Check out these links:
http://www.pcbsd.com --------%26gt; variation of the FreeBSD Unix, easy to learn on, uses minimal system resources [runs on slow computers]
http://www.opensuse.org -----%26gt; by Novell Software, variation of the Red Hat Linux with very easy hardware configuration, uses a lot of system resources
http://www.knoppix.org ------%26gt; Linux Live CD meaning no install required, just put the CD in the tray and boot the computer. Based on Debian Linux, which I am not a big fan of.
Final question: What are you trying to do in Unix? Server, programming, scripting, safer internet browsing? The list goes on. Choosing the distribution is the hard part, choosing the window system during the install is the next. After that it's like transitioning from MS to Mac, MS to Linux is similar. Windows to KDE, Gnome, or Xfce interface, or DOS to Bash and Batch to Shell. My suggestion is play with a live CD for a little bit to get the feel, then select and install a version on a computer at home, preferably a test computer but it could be installed after a repartition of your hard drive to even dual-boot along side Windows. Who knows, eventually you may never go back to MS anyways.
Reply:You can learn by yourself. search some sources to read.

Which four year school offers UNIX as a major/minor?
Which four year school offers UNIX as a major/minor? I am trying to find a school, but everything that I find is a two year school. Thanks.
Which four year school offers UNIX as a major/minor?
A four year school is not likely to offer a degree in a specific language or platform. What you can do is choose a four year program in computer science or engineering and then study that platform.
Ex. - When I got my masters in engineering, I specifically chose a track in software engineering. I further narrowed that focus into system design and implementation. The same principle applies to a B.A. or B.S. - You don't, for example, get a degree in international marketing, you get a degree in business with a focus in international marketing.
Hope that helps.
Reply:UNIX really isn't something you'd major in. Normally you'd learn to use UNIX as part of a program for system administration/IT, or programming. Just make sure they include some form of UNIX (Linux, SunOS, etc.) in the classes.
Also, nothing beats self-study. If you have an old PC lying around, download RedHat Linux for free and install it. If you buy one of those 'teach yourself Linux' books, many of them include a version of Linux as well.

What is the difference between UNIX, LINUX, DOS OPERATING SYSTEM?
Linux is modeled on Unix, but developed independently, and is free, open sourced software. Unix, in its many flavors is propriatery, although I think Sun might have open sourced their version of Unix, but I could be very wrong.
Linux / Unix are very powerful, multi-user capable systems, and can be run either from command line or through GUIs. I am not sure what limitations Unix has in terms of using the numerous GUIs that run on Linux.
I think Unix is more hardware demanding than Linux, but I could be wrong.
DOS is a command line OS, single user, much less powerful than Linux or Unix. Many commands for DOS were also present in (and copied from?) CP/M. Many Linux/Unix commands are different from those of DOS.

Can i get help regarding OS linux and unix .does these OS have soemthing equivalent to pws or IIS OR WINDOWSXP
I AM NOVICE INTO DESIGNING AND PROGRAMMING IN THE WEB.WHY DON'T YOU GUYS OUT THERE TELL ME MORE ABOUT THIS .
I found out that using pws in windows 98 and 2000 pro or IIS in windows xp ,we don't need to code a dynamic interactive stuff since i provides all these in the wizard as a temlate in other office applications.
But my newly hosted personal site was hosted in apache server which supports only linux and unix hence pws and iis work would go in vain although it looks good on the computer before its hosted or the files uploaded to my cpanel.
I am new to linux and no nothing of UNIX (does it have gui version too)
can you suggest some informative site about all this server stuff since its quite technically intricate for me atleast for the time being .

How to send messeges on unix LAN?
in our college we r learin UNIX which we have to connect using the command "telnet %26lt;ip address of server%26gt;
and while doin wen i entered the command "who"
a got all the users who r connected to that server..with their ip addresses
so my doubt is can i send any messeges to other users without installing any software....any command which sends messeges to other users...........plez suggest me
How to send messeges on unix LAN?
write %26lt;username%26gt; " your message "
example :-
$write tt1 "hello dear i am sending a message on the unix "
Reply:well you can use wall or rwall to send a msg to everyone logged in the server .
But when I was in college , used to have a very interesting command "talk"
the usage:
talk person [ttyname ]
person
If you wish to talk to someone on your own machine, then person is just the person's login name. If you wish to talk to a user on another host, then person is of the form `user@host'
ttyname
If you wish to talk to a user who is logged in more than once, the ttyname argument may be used to indicate the appropriate terminal name, where ttyname is of the form `ttyXX' or `pts/X'
When first called, talk contacts the talk daemon on the other user's machine, which sends the message
Message from TalkDaemon@his_machine...
talk: connection requested by your_name@your_machine.
talk: respond with: talk your_name@your_machine
to that user. At this point, he then replies by typing
talk your_name@your_machine
It doesn't matter from which machine the recipient replies, as long as his login name is the same. Once communication is established, the two parties may type simultaneously; their output will appear in separate windows

What is memory management in UNIX ?
Memory management is the act of managing computer memory. In its simpler forms, this involves providing ways to allocate portions of memory to programs at their request, and freeing it for reuse when no longer needed.
Virtual memory systems separate the memory addresses used by a process from actual physical addresses, allowing separation of processes and increasing the effectively available amount of RAM using disk swapping. The quality of the virtual memory manager can have a big impact on overall system performance.
Garbage collection is the automated allocation and deallocation of computer memory resources for a program. This is generally implemented at the programming language level and is in opposition to manual memory management, the explicit allocation and deallocation of computer memory resources.
In addition to standard memory management, DOS led to the development of programs known as memory managers. These move portions of the operating system outside their normal locations in order to increase the amount of memory available to other applications. Examples are EMM386, which was part of the standard installation in DOS's later versions, and QEMM. These allowed use of memory above the 640 kb barrier, where memory was normally reserved for ROMs, and high and upper memory.

XML DOM library in C++ UNIX?
Any idea that how can I manipulate (Adding and Removing) with XML nodes in UNIX C++? Any idea/ document about how to do the implementation using libxml or some other libs??? Any help will be appriciated.
XML DOM library in C++ UNIX?
You may want to look at the Apache Xerces project. They have a C (or C++) XML parser, which does DOM and SAX.

Where to download and install unix?
want to download, burn CD and install unix. New at this, and need open source site.
Where to download and install unix?
A couple of free distributions (of Linux) I recommend are:
1) SimplyMEPIS
Very nice and easy to install.
2) openSuSe (pronounced Sue'Sah)
This one also has a "Live" version, meaning you can actually run it from the CD without installing it to see if you like it.
Reply:google it.
Look for RedHat Linux
Linux is close enough to Unix that 99% of Unix programs run in it... and its free.
Reply:It depends on the linux distribution you want to use.
Check here: http://en.wikipedia.org/wiki/Linux_distr...
Reply:www.ubuntu.org
free, simple, enjoy

For starters, there are many flavors of free unix downloads but I tend to use the CentOS because it is basically Redhat without the licensing fees and what my employer prefers. Basically 99.9% of rpm's that will run on Redhat will also run on CentOS and all of the troubleshooting documents related to Redhat apply to CentOS as well. But they are all good!!! so try a few and see which you like best. Maybe you're adventurous and want to run more than one flavor on a single box, in that case check out the open source version of Xen....
And if you want true Unix on an i386 I do believe that Sun has open sourced it's Intel version of Solaris but you would have to confirm that by looking on www.sun.com
Reply:Try linux.org. They list almost all if not all distros available. Do some research before picking a distro so you can download one that most meets your needs.
Reply:Try this site www.download.com and search your desired software!
Reply:Just type in "unix" in your search bar, then look for "download unix".
Reply:Duh, On your computer.
Reply:Unix isn't free or open source.
Linux, on the other hand, is and a number of distributions are available. Most people start with Ubuntu, Debian, or Red Hat.

What are the features of Unix operating system?
Unix is a highly configurable, multi-tasking, multi user operating system created by Bell Laboratories. It is also very stable and network friendly. It is easily modified to accomodate most needs and can be the platform for many business, engineering, professional and communications applications. I hope this helps. Below are a couple of sites that have more information.

What is the fullform of unix?
Dennis Ritchie said it was a play on the Multics OS name. He created Unix, so his word is good enough for me.
I added the reference from Bell Labs (where Unix was created) below so that I had more evidence than just what I heard from Dennis around 1980 or so.
Reply:Full form of UNIX is UNiplexed Information Computing System (UNICS), later known as UNIX.
It is because, when the Unix was first developed in 1970s, it required the data and address buses to be uniplexed, i.e they were not multiplexed, hence it was named so.
Reply:Unix is just that ...Unix although when referring to members of the *nix family the * is used.
Unix (officially trademarked as UNIX®) is a computer operating system originally developed in 1969 by a group of AT%26amp;T employees at Bell Labs including Ken Thompson, Dennis Ritchie and Douglas McIlroy. Today's Unix systems are split into various branches, developed over time by AT%26amp;T as well as various commercial vendors and non-profit organizations.

I want to run a Unix shell script in the background not a terminal window?
I have a Unix shell script program that wants to run in the foreground terminal window. It runs fine in there, but it requires that the terminal always be open.
I want to run it as a background/service application so I do not have to keep logged in.
I want to run a Unix shell script in the background not a terminal window?
the command is
crontab -e
Look it up on the Internet on how to put an entry here to enter in a scheduled task.

Reply:Two things to do...
(1) You need to re-direct both the input and the output so it doesnt crash on you if it actually does require a terminal to be open while running. Typically, shorting them to /dev/nul or having some preset text files with some bogus inputs and something to grab the output may work. UNLESS the program is CURSES aware or an X-Windows or similar program - then you need to run it in a virtual x-windows windows that is not attached to a physical monitor of any kind.
(2) Add an ampersand (%26amp;) at the end of the command to make it run in the background, OR if you have superuser rights, put it into your crontab to run at specific time or times during the day.
Reply:add an ampersand (%26amp;) to the end of the command
Reply:Since you want to log out, you need to run:
nohup %26lt;command%26gt; %26amp;
Background jobs tend to terminate otherwise when you logout. Run man nohup for the grisly details.
Reply:Run the program you want running in the background like normal. Hold down ctrl+z in the terminal. This will stop the process currently running. Now type bg and hit enter. This will cause the last stopped process to run in the background.
