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.

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,…):

Copies a dir structure without the files in it.
If you want certain files out of a directory hierarchy, this will copy just the listed files, but will create the directory hierarchy in the new location ($DIR/)
Find all corrupted jpeg in the current directory, find a file with the same name in a source directory hierarchy and copy it over the corrupted jpeg file.
Convenient to run on a large bunch of jpeg files copied from an unsure medium.
Needs the jpeginfo tool, found in the jpeginfo package (on debian at least).
This command will copy files and directories from a remote machine to the local one.
Ensure you are in the local directory you want to populate with the remote files before running the command.
To copy a directory and it's contents, you could:
ssh [email protected] "(cd /path/to/a/directory ; tar cvf - ./targetdir)" | tar xvf -
This is especially useful on *nix'es that don't have 'scp' installed by default.
If you have lots of remote hosts sitting "behind" an ssh proxy host, then there is a special-case use of "rsynch" that allows one to easily copy directories and files across the ssh proxy host, without having to do two explicit copies: the '-e' option allows for a replacement "rsh" command. We use this option to specify an "ssh" tunnel command, with the '-A' option that causes authentication agent requests to be forwarded back to the local host. If you have ssh set up correctly, the above command can be done without any passwords being entered.
./* is for copying files starting with -
.[!.]* is for copying hidden files and avoiding copying files from the parent directory.
..?* is for copying files starting with .. (avoids the directory ..)
/path/to/dir the path to the directory where the files should be copied
Can also be used as a script. Input argument is /path/to/dir
in tcsh, replace .[!.]* with .[^.]*
