Question

My script that i have works just how I want it to, with one exception. I would like to be able to automatically set the unix group permissions to the directory and files that I create in my perl script.

Is this possible, or do i just have to resort to

chgrp <group> <directory>

after running my script?

You can use Perl’s chown function as such:

# Get the GID as a number 
my $gid = getgrnam("group");

# Change the ownership 
chown -1, $gid, $dir; # Or $file or @list_of_files depending on your need

You may need privileges to do this however, as stated in the docs.
