Git add, commit, and push in one function for Fish Shell

quickgit.fish

# How to git add, commit, and push using one function in friendly interactive shell (Fish Shell).
# Save this file within '~/.config/fish/functions' as 'quickgit.fish'. Create the directory if it does not exist.
# '--git-dir=$PWD/.git' Ensures that we run the git commands against the git project where we called the function

function quickgit # This is the function name and command we call
 	git --git-dir=$PWD/.git add . # Stage all unstaged files
	git --git-dir=$PWD/.git commit -a -m $argv # Commit files with the given argument as the commit message
	git --git-dir=$PWD/.git push # Push to remote
end

# Restart terminal, navigate to project, make changes, and now you can call 'quickgit "example message"'.
# Changes will now be added, committed, and push :).
