austin43:

As I understand it, umask is a built-in command in bash (I don't know about other shells). Not only that, but it only operates for the process that the shell is running in (I don't know about its descendents). So even if you do execute it, it will only affect the process that ends when the command returns to you.

You probably want to use the perl umask function (see umask documentation under perldoc perlfunc).
