Try this for a very basic list of commands. Sorry, it doesn't include such things as writing CDs or DVDs or downloading/upgrading programs or lots of things that can be done with the utilities that come with the standard desktop. Check out "Linux Cookbook" by Carla Schroder. Great book! -mj- Matthew A Coulliette wrote: Hi all, Every once in a while someone mentions that: "they use the command line for that", where "that" means almost "anything". Example: someone just mentioned that they use the command line for email. I was wondering if people that use the command line a lot could list a few of the programs they use and what they are used for. Example: Irssi: instant messenger for irc channels.

The Channels of a UNIX Command:
stdin (0) -> command -> stdout (1) and stderr (2)
The standard out of one command can be piped ( | ) into standard in of
another command. For example:
ls -al | grep joe lists all the files in the current directory
and searches for the string "joe" in the filenames and only prints
those that match..
ls | xargs -i grep joe {}
searches for the string "joe" within the body of all files in the
current directory, illustrating the use of pipe and the xargs command.
find . size +100000c print > big1s 2>&1
Finds all files in this and subordinate directories that are larger
than 100,000 bytes, sending both stdout and stderr to file "big1s".
