Git Tab Autocompletion for Commands in Bash

In OSX Bash you could use to autocomplete file paths. You can also use My Dotfiles to get tab completion for SSH hostnames based on ~/.ssh/config and many more commands.

You need to get the .git-completion.bash from Repository or you cand use this command in your terminal:

curl https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash -o ~/.git-completion.bash

Then you need to update your .bash-profile file with:

if [ -f ~/.git-completion.bash ]; then
  . ~/.git-completion.bash
fi

Now you need to restart your terminal and after you type git c then hit TAB key you can see all the git commands that start with c letter.

How to make it work with aliases

Let’s say you have aliases for:

alias g ='git'
alias gco = 'git checkout'

You can use __git_complete function from git-completion.bash which can be used to set up completion for aliases. Update your .bash-profile file with:

if [ -f ~/.git-completion.bash ]; then
  . ~/.git-completion.bash

  # Add git completion to aliases
  __git_complete g __git_main
  __git_complete gco _git_checkout
fi
