Iterate over all sub directories and print a list of which git repos have uncommitted changes.

git-status.sh

#!/bin/bash

# Loop through all files and directories
for dir in ./*
do

  # Skip files
  if [ -d $dir ]; then
  
    cd $dir;
  
    # Filter down to only git repos  
    if [ -d ".git" ]; then
      
      # Print repos that have uncommitted changes

      if [[ -n $(git status -s) ]]; then
        echo $dir;
      fi;
      
    fi;
    
    cd ..;
