I want to use the Unix command ckSum to generate a simple checksum for a file and store this for use in my program.

The system command returns success/failure {wait()} of whatever it executes but I want to get at the value...

$chkSum = system("cksum $file");

[download]

...the above returns either 0 or 256 depending on success/failure.

I think this is quite a basic thing to achieve but I'm lost.

Thanks

Mark
