Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

find -print0 and xargs -0

ps -e -m -o user,pid,args,%mem,rss | grep Chrome | perl -ne 'print "$1\n" if / (\d+)$/' | ( x=0;while read line; do (( x += $line )); done; echo $((x/1024)) );

Functions: cut grep
