Iterates through all of the git repos in the current directory and performs some git operation. The default is 'git status'.

gitall.sh

#!/usr/bin/env bash

GITCMD=status
if [[ -n $1 ]]; then
	GITCMD=$1
fi

echo

	(if [[ -d "$dir" && -d "$dir/.git" ]]; then
		cd $dir
		echo $dir
		git "$GITCMD"
		cd ..
		echo
