5 Effortless Ways to Check Perl Module Version

Checking the version of a Perl module is a common task for Perl developers. There are a few different ways to do this, but the most common is to use the `perldoc` command. To check the version of a module, simply type `perldoc -v ` at the command line. For example, to check the version of the `CGI` module, you would type `perldoc -v CGI`. This will print the version number of the module to the console.

Knowing the version of a module is important for a few reasons. First, it can help you to determine if you have the latest version of the module installed. Second, it can help you to troubleshoot problems with the module. If you are having problems with a module, checking the version can help you to determine if the problem is caused by a bug in the module or if you are simply using an outdated version. Finally, knowing the version of a module can help you to stay up-to-date on the latest features and improvements to the module.

In addition to using the `perldoc` command, there are a few other ways to check the version of a Perl module. One way is to use the `cpan` command. To check the version of a module using `cpan`, simply type `cpan -i ` at the command line. This will install the module if it is not already installed, and it will also print the version number of the module to the console. Another way to check the version of a Perl module is to use the `Module::Info` module. To use the `Module::Info` module, first install it using the `cpan` command. Once the module is installed, you can check the version of a module by typing `perl -MModule::Info -e ‘print Module::Info->version(“”)’` at the command line.
