Git: Display a list of recently checked out branches/tags/commits
#!/usr/bin/env bash
# Source: https://gist.github.com/jordan-brough/48e2803c0ffa6dc2e0bd
# Download this script as "git-recent" (no extension), chmod it to be executable and put it in your
# path somewhere (e.g. /usr/bin). You can then use it via `git recent` from inside any git repo.
# Examples:
# Interactive prompt for most recent 4 branches:
# $ git recent -n 5
# 1) master 4) deleted-branch
# 2) stable 5) improve-everything
# 3) fun
# Choose a branch: 2
# List mode (non-interactive):
# $ git recent -n 5 -l
# master
# stable
# fun
# deleted-branch
# improve-everything
# Verify branch existence:
# $ git recent -n 5 -l -e
# master
# stable
# fun
# improve-everything
# something-else
# # (notice "deleted-branch" removed from results)

@jordan-brough Would you be okay with officially releasing this as open-source? All this means is commenting here "I release the code above under the MIT license".

If you need this for windows, it works if you use 'Git for Windows':

  1. create a directory C:\Users<your_username>\bin
  2. in Git Bash, verfify you directory is in the path: echo $PATH
  3. copy the above file in C:\Users<your_username>\bin\git-recent

The git recent command will be available in CMD, Powershell, Git bash

@jordan-brough - This can be really useful as open source - Can you please verify the license is permissive?
