Script that looks at all images in a given location and checks if there are any references to each image. Useful for checking if images are being used by CSS for instance.

unused-images.sh

#!/bin/bash
DIR=.
if [ -n "$1" ]
then
  DIR=$1
fi

# Find image files in.
FILES=`find $DIR -type f | grep ".*\.\(jpg\|gif\|png\|jpeg\)"`

# Default searcher is grep. If Silver Searcher is installed, use that.
SEARCHER='grep -r -l '
if command -v ag
then
  # Sweet! Let's use Silver Searcher.
  SEARCHER='ag -l '
fi

# Loop over image files.
for f in $FILES
do
  if [[ -f $f ]]
  then
    name=$(basename $f)
    found=$($SEARCHER $name $DIR)
    if [[ -z $found ]]
    then
      echo $f
    fi
  fi
done

This works well, except when I'm using Silver Searcher (ag version 0.23.0, installed with homebrew) it outputs the location of ag (/usr/local/bin/ag). So if I pipe to xargs rm, ag is removed and I have to relink. I've played with the script a bit to see if I could fix it, but I'm not familiar with shell scripting. Any thoughts?
