mkdir - how do you use it	Can't Post

I need to create directories in by script, but what is the format of the second argument? The manpages say that the format is that of umask, but what's that? I've already tried 755, '755', 0755, etc.. but i keep getting a zivide-by-zero type error

I just read up on it and from what I undrstand umask is just short for the Unix Permission Mask, and the Unix Permission Mask is simply the permission. But to set a permission when using the mkdir you have to use permissions that are only similar to the ones that we really use like, 777, 755, and 666. 666 is 0666, 777 is 0777, and 755 is 022.

I was also suprise that 022 would be 755 but I just read it in two different books. Perl Cookbook, and Mastering Perl 5. Don't buy the second one.

I went to perl.com and I didn't find much other than what I read and told you but if you want to see go ahead, http://www.perl.com/cgi-bin/msearch.pl?searchfor=permission and
http://www.perl.com/cgi-bin/msearch.pl?searchfor=umask

Hi

$dir = 'cure'; #the name of the directory is cure
mkdir $dir,'0755';
chmod(0755, $dir);
