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.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
