Git Alias

If there is a common but complex Git command that you type frequently, consider setting up a simple Git alias for it. Aliases enable more efficient workflows by requiring fewer keystrokes to execute a command. It is important to note that there is no direct git alias command. Aliases are created through the use of the git config command and the Git configuration files.

git config --global alias.co checkout

Now when I use the command git co, it is just as if I had typed that longer git checkout command.

git co -b branch1

Output

Switched to a new branch 'branch1'

Creating the aliases will not modify the source commands. So git checkout will still be available even though we now have the git co alias.

git checkout -b branch2

Output

Switched to a new branch 'branch2'

Aliases can also be used to wrap a sequence of Git commands into new Git command.
