This is the code I have written 

#!/pgp/perl5/bin/perl
##Sample script to grep perl program output
#use strict;
#use List::MoreUtils qw(any);
use warnings;
use strict;
use feature qw{ say };

#Added env variable for exporting pgp LIB_PATH
$ENV{LIBPATH} = "/pgp/lib";

my %errors = (
    'input file not found' => sub {
        print "Bloody input file is missing...\n";
    },
    'signing key not found' => sub {
        print "meh, we're screwed..\n";
    },
    'no keys found' => sub {
        print "This doesn't need encrypting anyway...\n";
    },
        'file wiped successfully' => sub {
        print "Woo Hoo..\n";
    },
);

my $program_output3 = `pgp --args --verbose`;

chomp $program_output3;           # chomp any newline
$program_output3 =~ s/^\d+://;    # remove the digits/colon

$errors{lc $program_output3}->(); # lowercase, just in case
