I got tired of typing my password for my bitbucket repo so I looked up a way to use ssh keys but happened upon the osx credential keychain. I thought I had installed it all correctly by following along with what was instructed in the git-scm book but something bad happened...I can't use git at all!! I then went and rm'd the credential-osxkeychain but that didn't fix my issue, neither did uninstalling and reinstalling git.
If I go into a repo that I had previously pulled down, change a file and run git status it hangs indefinitely.
If I make a new directory, cd into it and run git init that will hang indefinitely as well.
When I run git without any arguments the following is printed out: Usage: git credential-osxkeychain <get|store|erase>. I already looked at my /Applications/Utilities/Keychain Acces.app but I couldn't find anything to change. At this point I just want git back...I'm fine with typing my password.
For reference I am using OSX 10.7.2
edited to add: which git returns /usr/bin/git
Try "git" status (with the quotes). If that works, you've aliased git to something else (probably alias git="git credential-osxkeychain"), and you should look in ~.profile to see if you can remove the alias.
(See the attached commentary for the debugging steps and eventual resolution).
