MKVmerge Batch Commands, Remove Tracks

To remove a particular track from an MKV file, the following notation should work:

mkvmerge -o output.mkv -atrack !2 input.mkv 

But I wasn't able to get the exclamation mart (meaning DON'T copy this track) to work. For some reason I kept getting "track not found" message. This should work with --vtrack or --strack (subtitle) or whatever.

Fortunately, I wanted to remove all the subtitles from my files, so I used the following instead:

mkvmerge -o output.mkv --no-subtitles input.mkv

If you only want to do this on one file, the mkvmergeGUI is fast and easy, but if you want to do it on a whole directory of files, you want to use this at the command line in a "For Loop," like so:

for i in *mkv; do mkvmerge -o ./newfiles/`basename "$i" mkv`.mkv --no-subtitles "$i" ; done

This will remove all subtitle tracks from all MKV files in the current folder, then put the new files in a previously-created sub-folder named "newfiles".
