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/
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,…):

Please note that sc will allow the SERVICE_NAME only, while net will allow both SERVICE_NAME and DISPLAY_NAME.
Note that the space between the = and the next word are important. Not very unixy, that.
Useful for making a CLASSPATH out of a list of JAR files, for example.
export CLASSPATH=.:$(find ./lib -name '*.jar' -printf '%p:')
due to bug can not comment
add |sh when you agree the list, I often use that method to prevent typos in dangerous or long operations
U have to make key exchange in order to avoid continuous password prompt.
Not that useful really, more novel. Can open up an awful lot of terminal windows.
Uses the PHP binary to check the syntax of all .php files in or below the current working directory. Really handy for doing that last minute check before you commit code to the repository.
"*" is important if you don't know exact name of file. Check it out and you'll see
Counts number of lines of code in *.h and *.cc files
depends on libjpeg-progs
But how to display path to found comments?
allows to grep very narrow subset of files
its useful to run dos2unix command later on them.
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
