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,…):

Command makes use of the Malware Hash Registry (http://www.team-cymru.org/Services/MHR/).
It parses the current directory and subdirectories and calculates the md5 hash of the files, then prints the name and sends the hash to the MHR for a lookup in their database.
The 3rd value in the result is the detection percentage across a mix of AV packages.
Finds a string in files recursively below the current directory on systems without the "egrep" and its "-r" functionality.
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name.
i.e.: logfile.1.gz > logfile.2.gz
I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.
Reuse the last parameter of the previous command line
First we accept a socket and fork the server. Then we overload the new socket as a code ref. This code ref takes one argument, another code ref, which is used as a callback.
The callback is called once for every line read on the socket. The line is put into $_ and the socket itself is passed in to the callback.
Our callback is scanning the line in $_ for an HTTP GET request. If one is found it parses the file name into $1. Then we use $1 to create an new IO::All file object... with a twist. If the file is executable("-x"), then we create a piped command as our IO::All object. This somewhat approximates CGI support.
Whatever the resulting object is, we direct the contents back at our socket which is in $_.
Adjust Google domain and window width
It works like a "tail -f" on several files.
Use the number keys 0-9 to set a baseline in the numbered window.
Pressing "b" let you scroll back in one of the windows.
Uses logger in a while loop to log memory statistics frequently into the local syslog server.
Command binds a set of commands to the F12 key.
Feel free to alter the dashboard according to your own needs.
How to find the key codes?
Then press the desired key (example: F5)
bind '"\e[15~"':"\"ssh [email protected]\C-m"""
bind '"\e[16~"':"\"apachectl -k restart\C-m"""
!* is all of the arguments to the previous command rather than just the last one.
This is useful in many situations.
Here's a simple example:
vi cd /stuff
[exit vi, twice]
expands to: cd /stuff
