Automated mkv merger

If you are addicted to merging mkvs as me you will need this too. 

Actually i made this for me but want to share it with the community.

I try to make this as parametric as i can (there are still some hard coded stuff but dont forget that i m too lazy to merge mkvs manually )

This is a two part script: automerge merges a single mkv and mergeall calls automerge for all the folders and merge them all.

I use mkvtoolnix-gui docker for the dependicies.

Bad news is i can i run it within the container from cli with

docker exec -ti mkvtoolnix-gui /bin/bash 
/config/config/automerge.sh -d "/somedirectory/"

but i want to run this with another script outside the docker. Cant achive that yet i appriciate any help and comments.

PS: I m not an linux or bash scripting expert i just can google and read. I think that i ve tested this script enough and beyond tests i merge over 30 movies with this but you should use it with caution.

#usage: automerge.sh -d "/input dir/" -o "/output dir/" -l eng
#you can omit any parameter
#if you omit -d and/or -o script will use currrent directory both for input & output
#-l parameter sets/overwrites the audio track language
#purpose of the script is to merge movie files, subtitles, posters and nfos automaticly with mkvmerge
#what does this script do:
#adds mkv file (just one file) in the input dir excluding sample without subtitle tracks
#adds turkish and english subs in the input dir (*_tr.srt *_eng.srt case insensitive)
#script will exit if tr sub not exists but continoue if eng sub not exists
#makes tr sub default track
#gets audio codec and channel info and put that to audio track name
#gets release name from the foldernae and put that to video track name
#adds *poster*.jp(e)g as attachment (there must be poster for movies. othervise script will exit)
#adds *.nfo as attachment (if not exists script will continue)
#script will exit if audio track lang is und this is where the -l option comes
#script will exit if multiple audio tracks exists
#and merges them with mkvmerge
#changes the output files permissions to 666
#moves the source files to another dir. sorry it is hard coded change it from the bottom of the script
