Here's a short cheat-sheet for UNIX. UNIX, that greatest of operating systems*, has reinvented itself through from a timesharing system in its earliest days to the well-known GNU/Linux and Mac OS X operating systems for personal computers. UNIX has also been used as a server operating system since its earliest days, and that use continues today with server variants such as OS X Server, (Free)BSD, and GNU/Linux distros like CentOS. Those interested in finding out more should read "The Art of UNIX Programming" by Eric S. Raymond.

CODE

cd : Change directory.
touch : Create a file
rm : Delete a file
rm -r : Delete a folder with files in
rmdir : Delete empty folder
ls : Lists files in directory (verbose '-la')
less : View contents of file (if not, try 'more')
ed : Line editor. (see also ex)
vi : Visual editor (F'naarr! F'naarr!)
emacs : Everything under the sun.
links : Text web browser. (if not, try 'lynx [if not, try "elinks"]')
telinit : Switch runlevels (safety modes) 1,2,3: cmdline; 5: gui.
ps : Processes list.
su - : Switch to root.
yum : Download/install packages (RPM)
apt-get : Download/install packages (Debian) (F'naarr! F'naarr!)
tar : Deals with tarballs.
man : Views manual pages on any command.
shutdown : Shuts down the system. (try 'shutdown now')
Also cat. Read the man page.

Useful locations
----------------
/home/x/ : Home directory for user x
/usr/bin/ : Most programs go in here
/etc/motd/ : The "Message of the Day", shown upon login
/usr/share/dict/words : A long list of words. (Linux only)

* Barring Plan 9, of course.

Thanks for the post! Will make a Server management forum later on and move this

Updated with ed, emacs, links, and telinit.

If you feel there's anything I've missed (I'm sure there's something!) please say so. I'm working on PCRE's at the moment.

How about:

CODE

ps aux               :   Show running processes
ls -al                 :   List files/folders in current location
cd locationhere  :   Navigate to the specified directory (ex: cd /etc/sysconfig)

How did I miss cd? .. and I'll also add the other two. Thanks!
