bash & mkvmerge batch processing

My aim: use mkvmerge to merge .srt subs with either a .avi or mp4. I can do this on mp4 files when all are in the same directory with

#!/bin/sh

for f in *.mp4; do

mkvmerge -o "${f%.mp4}.mkv" "$f" "${f##*.srt}"

done

If possible I would like to do this in one step with either mp4 or avi files. If needed, I can repeat the script to convert avi files.

Question: How can I alter the above to be recursive when movie and the corresponding subs are in separate directories?

Thanks.

Re: bash & mkvmerge batch processing

You could put your for loop inside another for loop which iterates over some directories.

Re: bash & mkvmerge batch processing

As for the first part of the question

#!/bin/bash

# do I need this
shopt -s extglob

# If no specific arguments were passed to script then it will check current dir for
# certain video extensions itself

(( $# )) || set -- *.@(mkv|mp4|avi|mov); [[ -e $1 ]] || { echo "No video files"; exit 1; }

while [ $# -gt 0 ]; do

    echo "$1"

    shift
done

and 2nd, maybe something along

f=woot
find . -name ${f}*.srt
./subs/woot.srt

or again some sort of extended glob.

shopt -s globstar
f=woot
ls **/*.srt
sub.srt  subs/woot.srt

ls **/${f}*.srt
subs/woot.srt
