Git shortcut to rebase onto another branch

Inspired by recent "git shortcut" cards I figured it would be nice to have one of these for rebasing a few commits onto another branch. The usual notation is prone to of-by-one errors as you have to either specify the commit before the ones you want to move or count the number of commits.

You may add this rebase-onto function to your ~/.bashrc:

function rebase-onto {
  commit=$(git log --oneline | fzf --prompt 'Select the first commit you want to move' | awk '{print $1}')
  branch=$(git for-each-ref --sort=-committerdate --format='%(refname:short)' refs/heads/ | fzf --prompt 'Select the branch to rebase onto' | awk '{print $1}')
  test_command="git rebase -i --onto $branch $commit~"
  read -p "Execute command '$test_command' (Y/n)? " choice
  case "$choice" in
    n|N ) echo "aborted.";;
    * ) eval "$test_command";;

It should reduce the amount of brain cells involved when rebasing onto a branch:


See the first card below for more context on this example.
