If you want to write some Web-based DBI scripts, You have to install CGI. pm module, you can use the perldoc command to check whether a Perl module has been installed. If this module has been installed, the perldoc command will display the documentation of this module, as shown below:

% Perldoc DBI
% Perldoc DBD: mysql
% Perldoc CGI
