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/
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,…):

Don't do this:
echo word | command
Using a bash "here strings" and "here documents" look leeter than piping echo into the command. Also prevents subshell execution. Word is also expanded as usual.
Useful contexts :
You are doing yoga or some other physical training in which you are holding a position.
Or you practice the pomodoro productivity technique.
Or your girlfriend said "We're leaving in 40 minutes".
sleep executes before espeak to give you a 5 seconds head start.
espeak is run in the background so it doesn't mess up the timing.
Then pipe to 'xargs ls' for a familiar listing, possibly using find's -print0 and xarg's -0 options.
You can write a script that does this :
remind <minutes> [<message>]
## like a boss.
Example 2 :
sudo vim /root/bin/
##uh... autocomplete doesn't work...
sudo ls /root/bin
##ah! that's the name of the file!
<ctrl+y> sudo vim /root/bin/ ##resume here! Thanks readline!
You may also use the $(which foo) variant instead of backticks. I personnaly have an alias ll='ls -l'.
