Question

I’d like to have a perl program that I can call with something like:

perl myProgram --input="This is a sentence"

And then have perl print the output to terminal, in this format

word1 = This
word2 = is
word3 = a
word4 = sentence

I’m usually a c/c++/java programmer, but I’ve been looking at perl recently, and I just can’t fathom it.

Use Getopt::Long and split.

#!/usr/bin/perl

use strict;
use warnings;
use Getopt::Long;

my $input = '';
GetOptions( 'input=s' => \$input );

my $count = 0;
for (split ' ', $input) {
        printf("word%d = %s\n", ++$count, $_);
}
