Git: Automatically moving a tag using a custom command

 |  200 words — 1 minute  |  git bash script

Ever find yourself moving a git tag to a new commit? You’ll probably know this procedure consists out of three steps;

  • Removing the existing tag from your origin

  • Manually moving the tag (using -f to allow moving)

  • Pushing the tag back your origin

Since this procedure is more cumbersome that it could be, behold, a quick and easy life hack to automate this process into a single custom command.

Before you start

  • Make sure you have a $HOME/bin directory

  • Make sure that directory is in your PATH

The script

  • Put this script in your $HOME/bin directory:

$HOME/bin/git-retag
#!/bin/bash

((!$#)) && echo No tag given, command ignored! && exit 1
if git rev-parse $1 >/dev/null 2>&1; then
    git push origin :refs/tags/$1
    git tag -f $1
    git push origin $1
else
    echo Tag not found in repo, are you sure you know what you\'re doing? && exit 1
fi

  • Make it executable by running chmod u+x $HOME/bin/git-retag

  • Enjoy!
