As you get acquainted with Pod::Usage, consider the normal layout of manual pages, and use it. You'll find that Pod::Usage::pod2usage provides the means to display just the SYNOPSIS portion or the whole manual. As for testing that the user gives you exactly one command-line "option":
#!/usr/bin/perl =head1 NAME name_of_utility_or_module =head1 SYNOPSIS brief example/template/summary of typical use(s), e.g.: prog_name -d prog_name -h prog_name -p foobar =head1 DESCRIPTION Paragraphs that describe the purpose, usage and various behaviors of the utility or module in suitable detail... =cut use strict; use Getopt::Std; use Pod::Usage; my %opt; getopts('dp:h', \%opt); pod2usage(2) if (keys %opt != 1); # die here if too many options were + given print "ok, here we go...\n"; if ( $opt{d} ) { # do this.. } if ( $opt{p} ) { # do that... } if ( $opt{h} ) { pod2usage(-exitstatus => 0, -verbose => 2); # exit & show full man + page }
