I have a bunch of files which need to be converted from .mp4 to .mpeg.one. A friend of mine had suggested me this simple script. However it doesn't work because filenames contain blank spaces.

Here is the script:

for f in $(ls *.mp4); do ffmpeg -i "$f".mp4 "$f".mprg; done

You don't need to use ls in this case. As a general rule, always try to use shell builtins and glob features instead of relying on external programs (e.g. ls) that can introduce problems with ugly workarounds.

Also, you shouldn't 'manually' append the extension to the input file name (the one you give to -i) and you should strip the extension on the output file.

So the command should be:

for f in *.mp4; do ffmpeg -i "$f" "${f%.mp4}".mprg; done
