So -f is an option that takes an argument. Before the getopts() function is called a default value of '-' is put into the hash %opt so that it can be determined whether the -f is used or not.
You should be able to read up on this, and also determine how to add options, by reading the man page:

i have made a script to perform so tasks and i managed to complete the tasks for all the options
the problem i am facing is that i can run the scripts individually but i would like to make it such that it can accept multiple options and give me the appropriate output

moosex::getopt::meta::attribute5.18
MooseX::Getopt::Meta::Attribute(3pm) User Contributed Perl Documentation MooseX::Getopt::Meta::Attribute(3pm)NAME
MooseX::Getopt::Meta::Attribute - Optional meta attribute for custom option names
VERSION
version 0.59
SYNOPSIS
package App;
use Moose;
with 'MooseX::Getopt';
has 'data' => (
metaclass => 'Getopt',
is => 'ro',
isa => 'Str',
default => 'file.dat',
# tells MooseX::Getopt to use --somedata as the
# command line flag instead of the normal
# autogenerated one (--data)
cmd_flag => 'somedata',
# tells MooseX::Getopt to also allow --moosedata,
# -m, and -d as aliases for this same option on
# the commandline.
cmd_aliases => [qw/ moosedata m d /],
# Or, you can use a plain scalar for a single alias:
cmd_aliases => 'm',
);
DESCRIPTION
This is a custom attribute metaclass which can be used to specify a the specific command line flag to use instead of the default one which
MooseX::Getopt will create for you.
This is certainly not the prettiest way to go about this, but for now it works for those who might need such a feature.
Use 'traits' instead of 'metaclass'
You should rarely need to explicitly set the attribute metaclass. It is much preferred to simply provide a trait (a role applied to the
attribute metaclass), which allows other code to further modify the attribute by applying additional roles.
Therefore, you should first try to do this:
has 'foo' => (traits => ['Getopt'], cmd_flag => 'f');
Custom Metaclass alias
This now takes advantage of the Moose 0.19 feature to support custom attribute metaclass aliases. This means you can also use this as the
Getopt alias, like so:
has 'foo' => (metaclass => 'Getopt', cmd_flag => 'f');
METHODS
cmd_flag
Changes the command-line flag to be this value, instead of the default, which is the same as the attribute name.
cmd_aliases
Adds more aliases for this command-line flag, useful for short options and such.
