I recently installed GitHub for Mac, the graphical Git client from GitHub, and also the command-line utility from its menu, shown below:
I was notified the command-line utility had been installed in /usr/local/github, but when I checked it had actually been put in /usr/local/bin/github - details shown below:
When I try to run git I get -bash: git: command not found, so I added export PATH=/usr/local/bin:$PATH to ~/.profile thinking it would solve the issue, but it hasn't - all that seems to be different is I can now start GitHub for Mac from the terminal by typing github.
Please could someone with more knowledge explain what's happening here?
The "GitHub for Mac" command-line utility is just a tool for launching "GitHub for Mac" in the current directory.
To install the git command line tool use either Homebrew (brew install git) or the Git for OS X installer.
From May 2013, you now have a different option:
See "Installing Git from GitHub for Mac"
you can now easily install Git for use on the command line, without needing to download any separate packages.
And whenever we update the version of Git included with GitHub for Mac, you'll get the changes automatically – no work required on your part!you may notice some changes to the Preferences window.
On the newly renamed "Advanced" tab, simply click "Install Command Line Tools".
You'll be prompted for an administrator password so that Git can be installed into
/usr/local/bin, and then you should very shortly see that it succeeded:
