Bash script to find problems with git repositories.
#!/bin/bash
# Author: Gonçalo Baltazar <me@goncalomb.com>
# I place this code in the public domain.
# Finds problems with git repositories that might lead to information loss
# in case of losing the local copy.
# Things like: uncommitted changes, untracked files, commits not pushed, etc.
# Put this script on your PATH. Then run 'git-problems' on a git repository or
# directory with multiple repositories.
# Tested on Linux Mint.
