Or declare @array within the while loop. This avoids making a copy of the array to make the anonymous reference.
#!/usr/bin/perl use strict; use warnings; use Data::Dumper; $Data::Dumper::Indent = 1; my %hash; while (my $rec = <DATA>){ chomp $rec; # declare the array my ($key, @array) = split(/ /, $rec, 2); $hash{$key} = \@array; } print Dumper \%hash; __DATA__ 1 2 3 4 5 6 7 8
$VAR1 = { '1' => [ '2 3 4' ], '5' => [ '6 7 8' ] };

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.
