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:
Valid JSON is a subset of YAML; no transformation is necessary; however, YAML has many syntax features that are not valid JSON, so you can't do the reverse as easily.

`up 3` will climb the directory tree by three steps. `up asdf` will do nothing, and returns exit code 1 as an error should.
Bash can accept '0x' and '0' notation for hexidecimal and octal numbers, so you just have to output the values.
I'm flat-out surprised that minecraft directory services require servers install multiple modifications to their server code, when the directories could fetch this information on their own.
Downloads the entire file, but http servers don't always provide the optional 'Content-Length:' header, and ftp/gopher/dict/etc servers don't provide a filesize header at all.
Another password maker, for human-unfriendly passwords. '-base64' output will make sure it it can be typed on a keyboard, though the output string length will always be a multiple of 4.
Requires sysfs mounted on /sys - may only be useful for Linux systems.
Could also use "printf '%-8s %s\n' $(basename $f) $(cat $f/address)" instead of echo.
Shows updated status in a terminal window for connections to port '80' in a human-friendly form. Use 'watch -n1' to update every second, and 'watch -d' to highlight changes between updates.
If you wish for status updates on a port other than '80', always remember to put a space afterwards so that ":80" will not match ":8080".
(also works on Ubuntu) Copies the 'install,' 'hold,' 'deinstall' and 'purge' states of packages on the remote machine to be matched on the local machine. Note: if packages were installed on the local machine that were never installed on the remote machine, they will not be deinstalled by this operation.
Substitute 'brown' with 'pink' or 'white' according to your taste.
I put this on my headphones when I'm working in an "open concept" office, where there are always three to five conversations going in earshot, or if I'm working somewhere it is "rude" of me to tell a person to turn off their cubicle radio.
