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/

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 commands compresses the "tmp" directory into an initrd file.
this command extracts an initrd files into the "tmp" directory
Copy changed files from remote git repository, _including binary ones_, staged and unstaged alike. Note that this command doesn't handle deleted files properly.
Get the list of changed files between revision 43 and HEAD revision: svn diff . -r43:HEAD --summarize
Strip extra 8 characters from every line: cut -c9-99999
Copy the listed files to home/me/destination: cpio -pvdmu ~/destination
Make a plain copy (-p), list files being copied (-v), create needed directories (-d), preserve modification time (-m), overwrite unconditionally (-u)
Archive all .sh files in a directory into a gzip archive.
.flac is the filetype.
/Volumes/Music/FLAC is the destination.
if you use disk-based swap then it can defeat the purpose of this function.
Clone linux installation.
Copy every file from current directory to destination preserving modification time.
This assumes you have the 'rpm', 'rpm2cpio' and 'cpio' packages installed. This will extract the contents of the RPM package to your current directory. This is useful for working with the files that the package provides without installing the package on your system. Might be useful to create a temporary directory to hold the packages before running the extraction:
mkdir /tmp/new-package/; cd /tmp/new-package
copies all files from the source disk / (skipping boundaries of mouted -in volumes) to /mnt/mydisk. Logical links are being preserved as well as devices, pipes etc. This can copy a MacOS X or Linux volume and keep it bootable. Note: its not suited to copy files with MacOS 9 style resources.
Copy data to the destination using commands such as cpio (recommended), tar, rsync, ufsdump, or ufsrestore.
Let the source directory be /source, and let the destination directory be /destination.
# cd /source
# cd ..
# find ./source -depth -print | cpio -cvo> /destination/source_data.cpio
# cd /destination
# cpio -icvmdI ./source_data.cpio
# rm -rf ./source_data.cpio
