I quickly wrote some sample code below that I hope would be more helpful to set your perl programming on the right track :-D
#!/usr/bin/perl use Getopt::Long; use Pod::Usage; # Recomend to use Pod::Usage along with Getopt::Long use strict; # Parse command line arguments and assign corresponding variables GetOptions ( 'f|fruit=s' => \( my $fruit = undef ), 'a|action=s' => \( my $action = undef ), 'g|greet' => \( my $greet = undef ), ); unless ( defined $action && defined $fruit ) { pod2usage( -exitval => 1, -output => \*STDERR ); } # do greeting print "Hello there!\n" if ($greet); # multiple fruit possible my @fruit = split /,/, $fruit; foreach (@fruit) { print "I will $action $_.\n"; # etc... } exit(0); __END__ =pod =head1 NAME fruit.pl =head1 SYNOPSIS fruit.pl [options] =head1 ARGUMENTS The -f and -a options are mandatory. The -g option is optional. =over 4 =item B<-f|--fruit [name]> Specify the fruit, multiple fruits possible, separate by comma =item B<-a|--action [name]> Specify the action to perform on fruit. =item B<-g|--greet> Print the greeting. =back =cut
Then you can run the program with command-line options:
perl ./fruit.pl -f apple,orange -a eat -g perl ./fruit.pl --fruit banana -action sell ...

Title:

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
