Regular Expressions and Private Arrays

Okay! Thanks for the help with the previous code!

I'm stuck again on something else now though. ^_^;

I have to add the values of an array @save that has numbers in it.
Code:
#! usr/bin/perl
use strict;

my $rules ="/Users/caitlin/scripts/challenge2.txt";
open my $FH, '<', $rules or die $!;
my @numbers;
my @save;


while (my $line = <$FH>){
        @numbers = split(m/[^0-9]+/, $line);
        push (@save, @numbers);

}

print @save;

It's not done yet because I have to add all the intergers in the array. The challenge2.txt contains text and numbers that I had to split. The result has empty spaces in it.

I need to take each result from the loop and add the next result to it. And as stated before, I'm dense... Smilie My attempts at it haven't amounted to executable code.

Help would be very much appreciated!
Thank you! Smilie

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list. Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)). FILES
