The difference seems to be the difference between: dash -c 'exec 1>/dev/null; echo closed 1>&2; exec 2>/dev/null; read' and bash -c 'exec 1>/dev/null; echo closed 1>&2; exec 2>/dev/null; read' Dash prints "closed" and exits immediately with error code 2. Bash prints "closed" and waits for input from the "read". Are we relying on non-portable shell behavior here? Andy -- http://wingolog.org/
