php

Sometimes I find it handy to randomly rename files with md5 hashes. Don't you ever feel like you need to do that? This script involves a line of PHP so to use it make sure you have PHP installed on your system.

It accepts either a file or a wildcard glob such as '*.jpg' (no quotes).

#!/bin/bash

while [ $# -gt 0 ]
do
	if [ -f "${1}" ]; then
		sz_basename=`basename "${1}"`
		sz_dirname=`dirname "${1}"`
		NEW_FILE=`php -r "echo md5('$sz_basename'.mt_rand());"`.${sz_basename#*.}
		echo "$1 => ${sz_dirname}/${NEW_FILE}"
		mv "$1" ${sz_dirname}/${NEW_FILE}
	fi
	shift
done
