The return code is also returned by the system() function. It looks to me
like the system isn't understanding what you're sending to it. Maybe you
could try single quotes?

Can you try this ?
system ("tar cvf ../test.tar *.grib");
if ($? == 0) {
print "\nSuccess!\n";
}
else {
print "\nUnsuccessful!\n";
}
The return code is in the perl $? variable. See perldoc perlvar for
details.

Subject: Testing for command success
I'd like to test the following command to see if it
ran successfully? Have no idea how or which variable stores
the success of a command ($!, $], $_ )?
system "tar cvf ../test.tar *.grib";
Tried:
if (system "tar cvf ../test.tar *.grib";) { print "\nSuccess!\n";}
got:
"Command not found"
Thank you in advance.
