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,…):

Creates a git repository in a predefined location.
git gc should be run on all git repositories every 100 commits. This will help do do so if you have many git repositories ;-)
if you cd into a directory then cd into another directory somewhere else then you run the cd - command you will go to the previous directory you was in!! To go back to the other directory just run it again. So if you are working in 2 different directories then this is the perfect command for you.
Install Ksuperkey one command in Kubuntu.
You must manually add ksuperkey to autostart in System Settings KDE.
In order to unrar several files in different subfolders, you just need to launch this command in your parent folder in order to have your files ready for manipulation and already extracted;
I did not put anything to delete the original rar files
I did not like two things in the submitted commands and fixed it here:
1) If I do cd - afterwards, I want to go back to the directory I've been before
2) If I call up without argument, I expect to go up one level
It is sad, that I need eval (at least in bash), but I think it's safe here.
eval is required, because in bash brace expansion happens before variable substitution, see http://rosettacode.org/wiki/Repeat_a_string#Using_printf
Here's an alternative if you don't have seq.
You can also remove the "&& pwd" if you don't want it to print out each directory as it moves up.
Assumes you've cd'd to the folder in which all your git repos reside; you could run it from ~ without -maxdepth, although that might make find take quite a while longer.
If you have several processor cores, but not that much ram, you might want to run
git config --global pack.threads 1
first, since gc-ing can eat lots of ram.
Changes dir to $1 and executes ls. As simple as useful
Had trouble with the other function, because of missing semicolons. (According to my bash on OS X)
I realise that this is just a reiteration of another entry (regardless of whether I came up with all this all by myself), but I would like present my additional alias' in context as a method of managing your directories. Rather convenient.
It gives a 'xcd' command for changing directory to one of CWDs of other ZSH processes (typically running in a terminal emulator). Useful for single-windowed terminal emulators like XTerm or Rxvt which don't have ability to pass CWD of one shell to another.
as alternative to cd $OLDPWD
If you have long and complicated folder names this might ease your work.
add this into .bashrc
switch to previous directory or toggle
Creates a directory and then cds into it directly
`up 3` will climb the directory tree by three steps. `up asdf` will do nothing, and returns exit code 1 as an error should.
Pros: Works in all Windows computers, most updated and compatible command.
Cons: 3 liner
Replace fcisolutions.com with your site name.
I wrote this a long time ago, wondering why this wasn't floating around somewhere out there (at least not where I could find).. this seems much more simple than multiple aliases and can cd out of directories easier.
