Hi All,

I have a question about the function chmod.

When you call chmod in a program, you just enter 

chmod '0755', $file;

But when you want to make the permissions variable, you need to oct it. Can anyone explain why?
I need to use the following piece of code to get the permissions of two files the same. 
use strict;
my $infile=shift;
my $outfile=shift;

my($mode,$uid,$gid)=(lstat($infile))[2,4,5];
my $chmod=sprintf("%04o", ($mode & 07777));
chmod oct($chmod),$outfile or die "Could not chmod";

# and do something with the uid and gid later...

Is there also a shorter way of doing it?

Thanks to clarify these misteries for me.
Does it has something to do with constants?
