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,…):

It would be good if anyone can shorten this to eliminate the duplicate query string.
git log --format=%H | tail -1 doesn't work anymore
Can anyone make a shorter one?
This doesn't work:
git log --reverse -1 --format=%H
Gets the authors, sorts by number of commits (as a vague way of estimating how much of the project is their work, i.e. the higher in the list, the more they've done) and then outputs the results.
Better tool for exporting git's repository is Git itself!
If like me you do a lot of front-end coding and you have a lot of clients that asks you some little modifications, then you send the modifications back to them in a zip file while ignoring the .git folder and .gitignore file, then copy this zip into your dropbox and send it back to them. They find out a new bug so, rince and repeat? You get the picture. It can be quite tedious.
In this example we search for 'vim' but vim doesn't have a project on github right now. That's ok, this command still searches for every project that has 'vim' in their description (forks, plugins, etc). To get XML or JSON output just replace 'yaml' in the url with 'xml' or 'json'.
What was the name of that module we wrote and deleted about 3 months ago? windowing-something?
git log --all --pretty=format:" " --name-only | sort -u | grep -i window
Display condensed log in a tree-like format.
This should work even if the output format changes.
List everyone who committed to a particular project, listed alphabetically. To list by commits, add -n to the shortlog.
You'll run into trouble if you have files w/ missing newlines at the end. I tried to use
PAGER='sed \$q' git blame
PAGER='sed \$q' git -p blame
to force a newline at the end, but as soon as the output is redirected, git seems to ignore the pager.
Figures out total line contribution per author for an entire GIT repo. Includes binary files, which kind of mess up the true count.
If crashes or takes too long, mess with the ls-file option at the start:
git ls-files -x "*pdf" -x "*psd" -x "*tif" to remove really random binary files
git ls-files "*.py" "*.html" "*.css" to only include specific file types
Based off my original SVN version: http://www.commandlinefu.com/commands/view/2787/prints-total-line-count-contribution-per-user-for-an-svn-repository
Initialized empty Git repository in /home/user/path/to/dir/.git/
I sometimes (due to mismanagement!) end up with files in a git repo which have had their modes changed, but not their content. This one-liner lets me revert the mode changes, while leaving changed-content files be, so I can commit just the actual changes made.
It deletes all removed files, updates what was modified, and adds new files.
Only shows files with actual changes to text (excluding whitespace). Useful if you've messed up permissions or transferred in files from windows or something like that, so that you can get a list of changed files, and clean up the rest.
Lists ONLY the files changed by the given HASH/HEAD/list of hashes, etc. The message, commit ID, author, etc. is not included
