In the Korn shell, I want to test to see if grep returns results (RC 0). What is the command to display the return code? I know in csh it is echo $status, but I can't remember what it is in ksh.

Thanks,

John

Thanks, Vlad!! I totally forgot what the command was. What is $# used for?

$# - number of arguments [to a script for example]
