Improved script for highlighting git repo folders which have unstated/uncommitted files. An improvement on the script for the Hazel rule created by @tylerhall: http://clickontyler.com/blog/2013/03/hazel-and-git. This improvement checks to see if the folder is actually a git repo and if not, doesn't bother processing any further.

dirname=$1
if [ -f $dirname ]; then
  dirname=`dirname $dirname`
fi

cd $dirname

if [ ! -d .git ]; then
  exit 1
fi

if git status | grep --quiet "working directory clean"; then
  exit 1
else
  exit 0
fi
