UNIX::Privileges

A module for handling UNIX privileges

Example

Synopsis:

use UNIX::Privileges;

UNIX::Privileges::userinfo($user);
UNIX::Privileges::chown($user, $file);
UNIX::Privileges::drop($user);
UNIX::Privileges::chroot($directory);

You can also do

use UNIX::Privileges :ALL;

userinfo($user);
chown($user, $file);
drop($user);
chroot($directory);

The :CH tag will import chown and chroot and the USER tag will import only USER.

Example usage:

use UNIX::Privileges;

UNIX::Privileges::chown("nobody", "test.txt");
UNIX::Privileges::drop("nobody");

Example with a chroot:

use UNIX::Privileges;

my $user = UNIX::Privileges::userinfo("nobody");
UNIX::Privileges::chown($user, "/tmp/test.txt");
UNIX::Privileges::chroot("/tmp");
# once in the chroot access to the system password file is lost
# therefore UNIX::Privileges::drop("nobody") will no longer work
# as the system cannot find the uid or gid of "nobody" anymore
# fortunately we already have this information in the $user var
# that we defined above by calling UNIX::Privileges::userinfo
# just remember you have to do this *before* creating the chroot
UNIX::Privileges::drop($user);

Installation

Assuming ypu have a working Rakudo installation you can install this with zef :

zef install UNIX::Privileges

Some of the tests won't be run unless they are run as 'root', and you may not be comfortable running a remote installer with escalated privileges, so you may want to checkout or otherwise download this package, run the 'root' tests with something like:

sudo zef test .

(assuming that the Rakudo toolchain is in the global PATH.)
