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,…):

This of course assumes that lesspipe is installed. You can view the contents of many, many types of files in this way. Once lesspipe is installed, add to your .bashrc
export LESSOPEN="| /usr/bin/lesspipe %s" less file.jar
export LESSCLOSE="/usr/bin/lesspipe %s %s"
Tested and works on Linux.
This works in bash. The "!!:0" limits the argument to man to be only the first word of the last command. "!!:1" would be the second, etc.
