Batch merge subtitles

[Shaorin]

I have a bunch of videos & subtitles with the same filename and I want to remux the video to include the subtitles in mkv container. I could use mkvmerge gui but that only does 1 file at a time and I want to do batch

GUI:

CLI:
for %%a in (*.mkv) do mkvmerge -o "output\%%a" "%%a" "%%~na.srt"

Or use forum search. Question comes up often.
