What Others Think

Rather than asign another variable to get the filename without suffix use a "string manipulations": % file="abcd.webm" ; echo ${file%%.*} abcd so, eg: for file in "$@"; do ffmpeg -i $file -vn -c:a copy ${file%%.*}.ogg ; done Also, your command seems to have a double 'ffmpeg' and all echo'ed.

The problem is that ffmepg can not demux the vorbis stream if there is non but rather a mp4 audio stream, in that case it will fail. Which is why this very short script only works on webm. I would like to see a script which determines the input codecs and acts accordingly :D
