How to Install Perl modules using Cpan

Hi,

Below is the steps to install perl modules using cpan(Comprehensive Perl Archive Network) in a CentOS machine.

The CPAN's main purpose is to help programmers locate modules and programs not included in the Perl standard distribution

It will act as a command line interpretor through which we can install perl modules.

You can get more details about Cpan in the wiki link http://en.wikipedia.org/wiki/CPAN.

sudo  perl -MCPAN -e shell

Above command will drop you in the CPAN shell.


cpan shell -- CPAN exploration and modules installation (v1.9402)
Enter 'h' for help.

cpan[1]> 

Now you can install a perl module. If you want to install a perl
module named Email::Sender, then you need to issue the below command.

cpan[1]> install Email::Sender

That is install module::name(Email is the module here and Sender is the name)

Once the installation shows as succesfull, then you can test it by listing installed perl modules using the command

# instmodsh

Available commands are:
   l            - List all installed modules
   m <module>   - Select a module
   q            - Quit the program
cmd? l
Installed modules are:
   Authen::SASL
