Thanks Martin for the report.
Here are the Perl commands defining the returned error code.
----------------------------------------------
print STDERR " - executing: $comm\n" if $debug;
if ($norun) {
print $comm,"\n";
$res = 0;
} else {
$res = system $comm;
$res = int($res/256);
}
if ($res != 0) {
print STDERR "Warning: program returned non-zero exit code
\#$res\n";
$retcode = $res;
}
(...)
exit($retcode);
----------------------------------------------
I do not understand why the original command's error code (127 in our case) is
turned to zero by changing it to "int($res/256)". I could remove this, but
before doing so, I would prefer to understand why it is done like this. Do you
have an idea ? If not, I will ask to the original author.
Have a nice day,
