GIT is version control technology created by Linus Torvalds. Getting GIT configured on your system requires a few steps to set up initially. To install and use GIT with a Mac OSX operating system, first download GIT from http://git-scm.com/
Once you have downloaded the files, run the .dmg file to install GIT on your machine.
Now once GIT is installed, it is a good idea to edit your .bash_profile file to enable you to use it more easily. The .bash_profile file is hidden, so first show your hidden files by using the following command in terminal:
defaults write com.apple.Finder AppleShowAllFiles YES
This will set finder to show all files. Now you must restart finder by using the following command in Terminal:
Finder should now restart and hidden files will be displayed. Next navigate to your home directory and enter into Terminal the following command:
If you look in your finder, because hidden files are displayed you should now be able to see the .bash_profile file. Open this file in your favourite text editor, and add the following:
Each directory specified in your .bash_profile file is separated with a colon. Save and close the file and head back into Terminal. You should now be able to run GIT from the Terminal by simply entering git as a command.
