It is really quite easy, and you would get the most from this forum if you tried to figure it out for yourself by reading the links. However, I will give you a start using
Getopt::Std, which has less features than
Getopt::Long but might be enough. It can be used in a couple of different ways, in this example we get the options set on the command-line into a hash:
use warnings;
use strict;
use Getopt::Std;
my %options;
getopts('abc', \%options);
while (my ($key, $value) = each %options)
{
print "Option: $key, value: $value\n"
}
print "Remaining arguments: @ARGV\n";
Here is a selection of command-line calls and results:
C:\>gash.pl -ac
Option: c, value: 1
Option: a, value: 1
Remaining arguments:
C:\>gash.pl -ab fred jim
Option: a, value: 1
Option: b, value: 1
Remaining arguments: fred jim
C:\>gash.pl -c -a fred jim
Option: c, value: 1
Option: a, value: 1
Remaining arguments: fred jim
