Hi, try instead: cat file | while read f ; do rm -f "$f" ; done In your command `file' is presented as 10,000 Maniacs MTV Unplugged - 01 - These Are Days.mp3 10,000 Maniacs MTV Unplugged - 02 - Eat For Two.mp3 10,000 Maniacs MTV Unplugged - 03 - Candy Everybody Wants.mp3 ... while the for-loop cuts the arguments at spaces. read reads the rest of the line in its last (and only -- in this case) argument into a single variable.
