Bash Script To Extract Subtitles From MKV file.

well ,some times I prefer to do things using the command line ,especially when logging into my server remotely ,so I created a little bash script to help me extract subtitles from mkv files using mkvextract ( you have to install  mkvtoolnix-cli) , still , the file extension need to be added though.
