perl function require

The require function in Perl is used to load external Perl modules or libraries into your Perl script at runtime. It takes a module name as an argument, and attempts to load the module by searching through the directories specified in the @INC array. If the module is found, it is loaded and made available for use in the script.

Here's an example of using the require function to load a Perl module named MyModule:

# Load the MyModule module
require MyModule;

# Call a function from the MyModule module
MyModule::my_function();

In this example, the require function loads the MyModule module, and then the my_function function is called from that module. Note that the require function does not import any functions or variables from the module into your script's namespace; to do that, you would need to use the use statement instead.
