A bash script to check if there are any git changes in the first level children of current directory. Only works on the same branch of the local copy.

git-check-dirs.sh

#! /bin/bash
for game in $(ls -1); do
  if [[ -d $game ]]; then
    cd $game
    git fetch
    HEADHASH=$(git rev-parse HEAD)
    REMOTEHASH=$(git rev-parse $(git branch --show-current)@{upstream})
    if [ "$HEADHASH" != "$REMOTEHASH" ]; then
      echo "Updating $game"
      git pull
    fi
    cd ..
  fi
done
