Short and to the point. This is probably too simple to deserve the title of "Tutorial", but this is where this is where some Monks look.

I've noticed that occassionally people try to use the command line, but don't quite "get" how to use modules and the import list. It's fairly simple. Use the -M command line switch, followed by the module name. For example, the following are equivalent:

use LWP::Simple; getprint( "http://www.perlmonks.org/" ); # command line: perl -MLWP::Simple -e 'getprint( "http://www.perlmonks.org/" )'

Some modules either require an import list be specified or are easier to use with an import list. In this case, use the -M switch followed by an '=', with import items separated by commas.

use CGI qw/:standard *table/; print start_table( { border => 2 } ); # command line perl -MCGI=:standard,*table -e 'print start_table({-border=>2})'

There, that wasn't too painful, was it?
