You have to roll your own sort routine. The example below splits each number on the "." and compares them section-by-section. Something like

sub sect { my @a = split /\./, $a; my @b = split /\./, $b; my $len = @b; if ( @a > @b ) { $len = @a; } foreach my $i ( 0 .. $len-1 ) { if ( $a[$i] > $b[$i] ) { return 1; } elsif ( $a[$i] < $b[$i]) { return -1; } } return 0; } my @s = ( "1.0", "3", "2.0.1", "", "1.0.1", "1.1", "1.0.2", "2. +0" ); my @t = sort sect @s; print "@t\n"; __DATA__ 1.0 1.0.1 1.0.2 1.1 2.0 2.0.1 3
there are probably more efficient ways to do this.

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 or How to display code and escape characters are good places to start.
