A neat way to switch git branches

When I work on repositories with many git branches I often forget the name of the branch I want to work on. So I made a gbs (git-branch-search) command in my zsh config!

# Fuzzy-find git branches and checkout afterwards.
gbs() {
  # List all branches in current repository.
  git branch -a |
  # Fuzzy find them using fzf. Place the search-bar at the bottom and add a nice header.
  # Render a preview of 'git log'  for each branch with bat.
  fzf --layout reverse-list --header="Select branch" \
      --preview "echo {} | sed 's/ //g' | xargs git log | bat --color=always --theme=gruvbox-dark -p" |
  # Finally checkout to the selected branch.
  xargs git checkout
}

Here it is in action
