Hi, currently, Im trying to run a shell script from perl and detecting for non-numeric return codes etc... how do i also detect if the file is not openable or executable or corrupted. Im a bit of a novice, started coding perl only last week and cant seem to find the exact answer in the perlopentut. the current syntax Im using is: 
$processor = \( 0+ `/aa/bb/ccc.ksh` ); 
        if (! $processor || $processor !~ /\d/){
...
}
