Hi all, I have 2 simple questions (maybe be very trial): 1. I saw some code put "umask 022;" in the near beginning of perl script. I understand that umask is for changing the file permission in unix/linux. However, if I put "umask 002" in the beginning of a perl script, after execution, the file permission is not changed to 002. So what is the purpose of using this command in perl since it does not change the actual file permission? 2. I tried the simple example in the GD.pm documentation: http://search.cpan.org/~lds/GD-2.35/GD.pm Perl shows me the errors on the line of "print $im->png;": Can't locate object method "png" via package "GD::Image" ..... The perl version in the server is: v5.8.8 What is the problem? And how should I debug it? Thanks in advance.
