Re: List of Command Line Tools

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!

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. Thanks.

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".
