#!/usr/bin/perl sub getFileSize($) { return -s $_[0]; } sub test($) { print "The following file called " . $_[0] . " has a file size of " . getFileSize($_[0]) + " bytes."; } test("file", "input.txt"); test("file", "/input.txt"); test("file", "\\input.txt"); exit; # Short version print -s 'input.txt'; print -s '/input.txt'; print -s "\\input.txt";
