Bash: Script for finding files by mime-type

Forking (exec) is expensive. This runs the file command only once, so it is fast:

find . -print | file -if - | grep "what you want" | awk -F: '{print $1}'

or

locate what.want | file -if -

check man file

-i    #print mime types
-f -  #read filenames from the stdin

#!/bin/bash
find $1 | file -if- | grep $2 | awk -F: '{print $1}'
