What is pipes and sockets in Perl?

Pipes and sockets are integral concepts in Perl that facilitate inter-process communication (IPC). They allow different processes to communicate with each other by sending and receiving data, enabling coordination and data exchange in a variety of applications.

Pipes in Perl

A pipe in Perl is a unidirectional communication channel that allows one process to send data to another. The data is typically sent through the standard input/output.

Here's an example of how to use pipes in Perl:

# Creating a pipe open(my $pipe, '|-', 'sort') or die "Cannot open pipe: $!"; print $pipe "banana\napple\ncherry\n"; close($pipe);

Sockets in Perl

Sockets provide a way for processes to communicate over a network. They can be used for both client-server architectures, allowing remote communication across different machines.

An example of using sockets in Perl is shown below:

use IO::Socket; # Creating a socket my $socket = IO::Socket::INET->new( PeerHost => 'localhost', PeerPort => '3000', Proto => 'tcp' ) or die "Could not create socket: $!\n"; # Sending data print $socket "Hello, World!\n"; close($socket);
