It sounds like it's deadlocking because ls wants to output to the stream, but the stream's buffer is full. ls -l would produce more output than -h or -1 in most cases. So you can probably pass :wait NIL to RUN-PROGRAM so that it returns before ls has exited, and read from the stream so ls can finish writing. > Oh, and running the same commands at the shell prompt works of course, > and the output and exit status is similar. > > > Bj�rn > -- -Tim
