Описание тега git-alias
With aliases, you can avoid typing the same commands over and over again. Aliases were added in Git version 1.4.0.
To show how to use Git aliases, suppose you wish you could write git ci instead of git commit. You can achieve this by adding the following section to ~/.gitconfig:
[alias] ci = commit
Some people are uncomfortable editing the config file themselves. They can edit the config by calling git config alias.ci commit instead.
If you want to have the alias available everywhere on your local machine, you can either - edit ~/.gitconfig, or - use the --global flag:
git config --global alias.ci commit
