Dear Monks

The following snipet of code , works fine
But how can I trap the exit code of the program check_nrpe
Which could be 0 , 1 , 2 or 254

open(CMD, "/local/nagios/libexec/check_nrpe -H $host|") or dir $!;
@CMD=<CMD>;
close(CMD);
[download]

I think I should be using fork or waitpid
but not sure how ?.

Thanks

Matt
