G'day FloydATC,

Perhaps something like this would be more to your liking:

$ perl -Mstrict -Mwarnings -le ' my @vlans = (2, 3, 4, 7, 10, 11, 12, 20); my $last = $vlans[0] - 2; my @ranges; push @{$ranges[$#ranges + ($_ - $last > 1)]}, $last = $_ for @vlan +s; print join ",", map { $_->[0] == $_->[-1] ? $_->[0] : join "-", @{$_}[0, -1] } + @ranges; ' 2-4,7,10-12,20

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.
