Question

My file contains

a: b
d: e
f: a:b:c
g: a
   b
   c
   d
   f:g:h
h: d
   d:dd:d
J: g,j

How can I parse this file into lefthand side values into one array and right hand side to another array? I tried with split, but I am not able to get it back.

I want to store them into hash.

Howzabout this:

#!/usr/bin/perl
use warnings;
use strict;
my $s = 
q/a: b
d: e
f: a:b:c
g: a
   b
   c
   d
   f:g:h
h: d
   d:dd:d
   f
/;
open my $input, "<", \$s or die $!;
my @left;
my @right;
while (<$input>) {
    chomp;
    my ($left, $right) = /^(.):?\s+(.*)$/;
    push @left, $left;
    push @right, $right;
}
print "left:", join ", ", @left;
print "\n";
print "right:", join ", ", @right;
print "\n";
