How has support for file permission handling (umask) changed across recent Perl versions?

Support for file permission handling, specifically umask, has evolved across recent Perl versions. The umask function in Perl allows developers to define the default permissions for newly created files and directories, ensuring better security and control over access. Over the years, enhancements and bug fixes have been made to improve its behavior and consistency.

Example of umask in Perl

#!/usr/bin/perl use strict; use warnings; # Get the current umask my $current_umask = umask(); print "Current umask: $current_umask\n"; # Set a new umask umask(0022); # Sets the umask to allow read/write for owner and read for group/others print "New umask set to: 0022\n"; # Creating a new file with the new umask open my $fh, '>', 'example.txt' or die "Cannot create file: $!"; print $fh "Hello, World!\n"; close $fh; # Check file permissions use File::stat; my $file_stat = stat('example.txt'); printf "Permissions: %o\n", $file_stat->mode & 07777; # Get file permissions in octal
