Here is a problem with 2.6.10: while read file; do mplayer $file ; done <mediafiles.txt or tail -n93 mediafiles.txt | while read file; do mplayer $file ; done for each file path in that text file I get: Failed to open /dev/rtc: Permission denied (it should be readable by the user.) In addition the audio pcm level is set to zero (presumably by mplayer). This does work: for file in `cat mediafiles.txt`; do mplayer $file ; done but discovering and fixing code now broke will be unpleasent.
