for loop work at multiple directory depth

I have the following for loop in bash:

for file in "$1"/*PM.mov ; do 
    ffmpeg -i "$file" -an -f framemd5 "${file}.framemd5.txt"
done

I want to adjust it so that it will run on any *PM.mov file in a given directory regardless of the directory depth of that file. Right now the loop only runs on the top level of the directory. How do I change that?

Two possibilities:

  • Use globstar (and nullglob while we're at it):

    shopt -s globstar nullglob
for file in "$1"/**/*PM.mov ; do 
    ffmpeg -i "$file" -an -f framemd5 "${file}.framemd5.txt"
done

  • Use find properly (but the previous one is better, as it's only a minor change to your code):

    find "$1" -type f -name "*PM.mov" -exec sh -c 'file=$1; ffmpeg -i "$file" -an -f framemd5 "$file.framemd5.txt"' sh {} \;

use the find cmd

for file in $(find $1 -name "*PM.mov") ; do 
    ffmpeg -i "$file" -an -f framemd5 "${file}.framemd5.txt"
done
