What are Perl modules and how do I use CPAN?
Perl modules are reusable packages of Perl code that can be used to extend the functionality of your Perl programs. CPAN, the Comprehensive Perl Archive Network, is a repository of Perl modules that you can easily install and use.
How do I install a module from CPAN?
You can install a module from CPAN using the command line. Just type cpan Module::Name
, replacing 'Module::Name' with the name of the module you want to install.
Are there any prerequisites for using CPAN?
Generally, you need to have Perl installed on your system. It's also helpful to have the CPAN client configured, which can be done by running cpan
in your terminal for the first time.
Can I find documentation for the modules?
Yes, each module on CPAN usually has its own documentation. You can access it by using the command perldoc Module::Name
after installation.
