perl system command return code
- by Mel
I have a script that has been running for over a year and now it is failing:
It is creating a command file:
open ( FTPFILE, ">get_list");
print FTPFILE "dir *.txt"\n";
print FTPFILE "quit\n";
close FTPFILE;
Then I run the system command:
$command = "ftp ".$Server." < get_list | grep \"\^-\" >new_list";
$code = system($command);
The logic the checks:
if ($code == 0) {
do stuff
} else {
log error
}
It is logging an error. When I print the $code variable, I am getting 256.
I used this command to parse the $? variable:
$exit_value = $? >> 8;
$signal_num = $? & 127;
$dumped_core = $? & 128;
print "Exit: $exit_value Sig: $signal_num Core: $dumped_core\n";
Results:
Exit: 1 Sig: 0 Core: 0
Thanks for any help/insight.
