oct Returns the octal representation of the number specified. If you are not familiar with octal, it is a number system in base 8 (0 to 7) that is used primarily in unix for file permissions; it's a quick way of specifying what value you should chmod a file to.

$output = oct(n);

$output - The octal representation of the number n.
n - A literal decimal number or a Form Processor variable

Example:

# takes read permission input and returns an octal number for them; chmod value

# global permissions

if ($user_r eq "checked")

 $user = $user | 4

endif

if ($user_w eq "checked")

 $user = $user | 2

endif

if ($user_x eq "checked")

 $user = $user | 1

endif

$perm = oct($user);
