How do you use cross-platform issues (Windows, macOS, Linux) with a short example?

When developing Perl scripts that are intended to run on multiple platforms such as Windows, macOS, and Linux, it is essential to consider differences in file paths, line endings, and system commands. Here’s a brief example demonstrating how to handle file paths in a cross-platform manner:

use strict; use warnings; use File::Spec; my $filename = 'example.txt'; # Create a cross-platform file path my $filepath = File::Spec->catfile('path', 'to', $filename); # Open the file open my $fh, '<', $filepath or die "Cannot open file: $!"; # Read the file content while (my $line = <$fh>) { print $line; } close $fh;
