I was surprised to find out my ‘git’ command didn’t work after upgrading to Lion.
It is still there (verify by checking for this directory: /usr/local/git/bin), just needs to be mapped.
I was able to find out that the git installer uses paths.d to add it to the path.
I went to /etc/paths.d and did ls – but there was not git file.
sudo vi git
enter /usr/local/git/bin at the top of the file (if new to vim, hit ‘I’ to enter ‘insert mode’)
hit escape – type :wq to save and quit
open new terminal – run ‘which git’
Should work now
