Thank you, the for loop did the trick! Why do I need the test command?

The while loop produced some strange results. It only processed half the files and gave read/write permissions for output files to root (?)

And, just curious, what is the difference between

Code:
while read a; do command $a; done

and
Code:
while read a; do command ${a}; done

?

NAME
plaympeg - MPEG audio (MP3) and video (MPEG-1) player SYNOPSIS
plaympeg [options] file ... DESCRIPTION
plaympeg is an MPEG audio and video player that uses the SDL MPEG Player Library. It can play back MPEG audio (layer 1, 2 and 3), MPEG video (MPEG-1) and MPEG system (audio and video combined) files. MPEG-2 video files (as found on DVDs) are not supported. The video player works best on a 16 bit color depth X11 display, it works on other color depths with reduced speed as well. You'll need a CPU with 300 MHz or more to play back an MPEG system stream with 25 frames per seconds (fps) at full speed. OPTIONS
--help Show short usage information --noaudio Don't play the audio stream (if available) --novideo Don't play the video stream (if available) --fullscreen Play the MPEG video stream in fullscreen mode (this requires root privileges or a setuid plaympeg binary) -2, --double Play the MPEG video stream at double size -l, --loop Play the stream (audio or video) over and over again -v N, --volume N Set the volume of the audio stream to N% (N in the range of 0 to 100) -s S, --scale S Play the MPEG video stream at S size SEE ALSO
