Can someone tell me what's wrong here?
sub processfile {
my $script = "/export/home/limo/Perl/exfields.pl -e";
my ($file, $list) = @_;
my %hash;
my @list = (split /,/, $list);
foreach my $arg(@list) {
open(FILE, "$script $arg $file |") or die "System error: $!\n";
while (<FILE>) {
chomp;
# print "$_\n"; returns expected results
my @array = split;
# printing each array element also passes here
$hash{$arg} = [@array];
push (@{ $hash{$arg} }, @array) unless /^\#|none|unkno/i;
}
}
foreach my $keys( sort keys %hash) {
print "@{ $hash{$keys} }\n";
# print statement here returns 1 "value "value" pair per key
}
close FILE;
return %hash;
}
Printing passes up until either the point where I populate the hash or try to print each key/value. What am I doing wrong here? FWIW, I am using Cookbook, recipe 11.2, pg. 372, for example.
