Hi there,

I loaded a bunch of configuration lines into a hash called $Input
now I am searching the hash to make sure specific lines are there.

I want to print "NO" unless there is a match to the following ""check $ip
here";

but $ip could be the range as shown below.

so a key like "check 2.2.2.2 here" would be accepted and NO would *not* be
printed and if the hash has a key with "check 2 here" then a NO *would* be
printed.

my $ip = "[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+";
print CHANGE "NO\n" unless exists $Input{"check $ip here"};


Cheers,

Noah

Untested code.

# Always...
use strict;
use warnings;

my %ip = ...;

#Get the lines as an array.
my @lines = keys %ip;

# Slight modification to the regex. Someone else's reply will probably
have a more elegant method.
my $ipSearch = qr/[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}/;

# Use variables for filehandles.
open my $CHANGE, "> $changeFile" or die;
print CHANGE "NO\n" unless ( grep ( $ipSearch, @lines ) );
.
