What are good alternatives to file permission handling (umask), and how do they compare?

When it comes to file permission handling in Perl, the traditional method using umask can sometimes be limiting or present certain challenges. Here are some good alternatives that can provide more control and flexibility in managing file permissions:

• Set Permissions Directly: Instead of relying on umask, you can specify file permissions directly when creating files.
• Using the File::chmod Module: This Perl module allows you to change file permissions easily after file creation.
• Environment Variable Configuration: Instead of setting umask, configure file permission settings through environment variables for more dynamic control.

Each of these alternatives offers specific advantages:

• Directly setting permissions provides precise control over what permissions are assigned.
• Using the File::chmod module simplifies permission changes with an easy-to-use interface.
• Environment variable configuration allows permissions to be adjusted without code changes.
