Recursively walks a directory and perform a git pull (if dir is a git repo). Ignores non-git directories.

git-pull

#!/bin/bash

dir="$1"
display_prefix="$2"

# No directory has been provided, use current
if [ -z "$dir" ]
then
    dir="`pwd`"
fi

# Make sure directory ends with "/"
if [[ $dir != */ ]]
then
	dir="$dir/*"
else
	dir="$dir*"
fi

# Loop all sub-directories
for f in $dir
do
	# Only interested in directories
	[ -d "${f}" ] || continue

	# Check if directory is a git repository
	if [ -d "$f/.git" ]
	then
    echo -n "Pulling "
    echo -en "\033[0;34m"
    echo -n $display_prefix
    echo -n `basename $f`
    echo -en "\033[0m"
    echo -n "... "

    git -C $f pull --rebase --prune --quiet &> /dev/null
    if [ $? -eq 0 ]
    then # everything is good
      echo -en "\033[0;32m"
			echo -n "✔ "
      echo -e "\033[0m"
    else # there are local changes
      echo -en "\033[0;31m"
      echo -n "✘ "
      echo -e "\033[0m"
    fi
	else
		# recurse into sub-directory
		git-pull $f "${display_prefix}${f##*/}/"
	fi
done
