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:
url can be a working copy or url to a svn repository, revision is any valid revision number for that branch.
It requires inkscape 0.46 and lxml packages
gps data from geocaching.com is provided for free in .loc format.
Certain codecs in high res don't play so well on my Dell Mini 9. Using this command, I can play just about anything and it keeps the sound in sync to boot!
Highlights the search pattern in red.
Also works with files:
To decrypt use the -d option:
echo SGVsbG8gd29ybGQK | base64 -d
A script that checks if your environment is correctly configured for using cobbler.
Add a repo to cobbler. To download all the repository contents the command is:
Lam is a command available on Bsd (I've tested it on OpenBSD).Is useful for laminate a file line by line. The -f option set the field width ( -f min.max ).
download a specific file with -f to not display errors and -O to write output to a file named as the remote file.
There was another line that was dependent on having un-named screen sessions. This just wouldn't do. This one works no matter what the name is. A possible improvement would be removing the perl dependence, but that doesn't effect me.
Basically an improvement on an earlier ethtool command line.
Not a discovery but a useful one nontheless.
In the above example date format is 'yyyymmdd'. For other possible formats see 'man date'.
This command can be also very convenient when aliased to some meaningful name:
alias mkdd='mkdir $(date +%Y%m%d)'
Lndir create from source directory to destination directory a full symlink tree of all contents of source directory, really useful for propagate changes from a directory to another.
Look search for lines in a file that beginning with a given string.
Same as $ grep ^n /etc/passwd
You can also use sha1sum and variants for longer passwords
Yields entries in the form of "/dev/hda1" etc.
Use this if you are on a new system and don't know how the storage hardware (ide, sata, scsi, usb - with ever changing descriptors) is connected and which partitions are available.
Far better than using "fdisk -l" on guessed device descriptors.
