commandlinefu.com is the place to record those command-line gems that you return to again and again.
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.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

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.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

Run "ps -x" (process status) in the background every hour (in this example).
The outputs of both "nohup" and "ps -x" are sent to the e-mail (instead of nohup.out and stdout and stderr).
If you like it, replace "ps -x" by the command of your choice, replace 3600 (1 hour) by the period of your choice.
You can run the command in the loop any time by killing the sleep process. For example
2925 ? S 0:00.00 sh -c unzip E.zip >/dev/null 2>&1
11288 ? O 0:00.00 unzip E.zip
25428 ? I 0:00.00 sleep 3600
14346 pts/42- I 0:00.01 bash -c while true; do ps -x | mail pascalv; sleep 3600; done
643 pts/66 Ss 0:00.03 -bash
14124 pts/66 O+ 0:00.00 ps -x
