mkvextractTracks.sh

#!/bin/bash -e



# a script that extracts the subtitle file of every mkv movie file and saves it with the same name

# copy to the folder where the mkv files live and run "./mkvextractTracks.sh" in terminal

# options: [trackID]

# example: ./mkvextractTracks.sh 1

#

# info:

# mkvextract is used to extract the subtitles, so mkvtoolnix app (which contains the mkvextract binary) is used:

# https://mkvtoolnix.download/downloads.html

# please adjust below path to point to mkvextract or this script won't work

extractorPath='/usr/bin/mkvextract'

# Ensure we're running in the location of the script.
cd "`dirname $0`"
