How do I handle logging in Perl scripts

Logging in Perl scripts is an essential practice for troubleshooting and monitoring the behavior of your application. It allows you to capture important events, errors, and debugging information. The following example demonstrates how to implement basic logging in a Perl script using the `Log::Log4perl` module.

#!/usr/bin/perl use strict; use warnings; use Log::Log4perl; # Initialize Log::Log4perl Log::Log4perl->init(\ q{ log4perl.rootLogger = DEBUG, LOGFILE log4perl.appender.LOGFILE = Log::Log4perl::Appender::File log4perl.appender.LOGFILE.filename = my_log.log log4perl.appender.LOGFILE.layout = Log::Log4perl::Layout::PatternLayout log4perl.appender.LOGFILE.layout.ConversionPattern = %d [%p] %m%n }); my $logger = Log::Log4perl->get_logger(); # Log messages with different severity levels $logger->debug("This is a debug message"); $logger->info("Informational message"); $logger->warn("This is a warning message"); $logger->error("An error has occurred"); $logger->fatal("A fatal error occurred");
