How can I handle multiple processes in Perl

Handling multiple processes in Perl can be accomplished using the `fork` function, which allows you to create child processes. These child processes can run concurrently with the parent process, making it an effective way to perform parallel processing tasks.

#!/usr/bin/perl use strict; use warnings; my @pid; for (1..5) { my $pid = fork(); if (!defined $pid) { die "Fork failed: $!"; } elsif ($pid == 0) { # This is the child process my $process_id = $$; # Get the current process ID print "Hello from child process $process_id\n"; exit(0); } else { # This is the parent process push @pid, $pid; # Store the child pid } } # Wait for all child processes to finish foreach my $child (@pid) { waitpid($child, 0); } print "All child processes completed.\n";
