That's more of a shell scripting question than an ffmpeg question, but
here we go, using a subdirectory for the results (so they don't mix
with the originals):

$ mkdir flac
$ for infile in *.mkv; do outfile=flac/${infile%.mkv}'(flac)'.mkv; echo ffmpeg -i "$infile" -c:v copy -c:s copy -c:a flac "$outfile"; done

(Untested.)
