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.
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
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,…):

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:
This prevents access to old CGI code
This takes a picture (with the web cam) every 5 minutes, and send the picture to your e-mail.
Some systems support
mail -a "References: "
so that all video surveillance emails are grouped in a single email thread.
To keep your inbox clean, it is still possible to filter and move to trash video surveillance emails (and restore these emails only if you really get robbed!)
For instance with Gmail, emails sent to email@example.com can be filtered with "Matches: DeliveredTo:firstname.lastname@example.org"
Access a random news web page on the internet.
The Links browser can of course be replaced by Firefox or any modern graphical web browser.

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
You have mail in /mail/pascalv
This will send the web page at $u to email@example.com . To send the web page to oneself, firstname.lastname@example.org can be replaced by $(whoami) .
The "charset" is UTF-8 here, but any alternative charset of your choice would work.
`wget -O - -o /dev/null $u` may be considered instead of `curl $u` .
On some systems the complete path to sendmail may be necessary, for instance /sys/pkg/libexec/sendmail/sendmail for some NetBSD.
