It works with other commands, but not this one. It simply creates the output file with nothing inside it. Nik-Lz Often this is because the command is sending all its output on stderr.
If gcc is generating error messages, this seems likely. See Slothworks comment for how to capture stderr instead of stdout. I have a problem that it stops writing when the file reaches about 8MB.
