Actually both will work although yours is probably the better one to use (shorter and less confusing). In Cliff's answer stderr gets redirected to where stdout was going (which is superfluous in this context), then stdout gets redirected to /dev/null. To redirect both stdout and stderr to /dev/null you'd have to reverse the order: >/dev/null 2>&1 Mark.
