You understand sort well, so there's not much efficiency to be gained, I think.
However, I would have used some complex data structure for readability. This also removes the need for temporary variables. (but adds an array)
my @data = sort { $a->[7] cmp $b->[7] || $b->[6] <=> $a->[6] || # '' == 0 $a->[0] <=> $b->[0] || $a->[1] <=> $b->[1] || $a->[2] <=> $b->[2] || $a->[4] cmp $b->[4] || $a->[3] cmp $b->[3] } map { [ /^(\d+)(\D+)(\d+)(\D*)R(\d+)(B?)(\d*)\.(\w+)$/ ] } <DATA>; print "$_->[0]$_->[1]$_->[2]$_->[3]R$_->[4]$_->[5]$_->[6].$_->[7]\n" f +or @data;
I've made some mistake in there, but I leave it up to you to find and fix it. For some reason, my version puts 113B28R2.ras two places too high (top==0) in the array.

I think my version is more readable, and threrefore more reliable and maintainable (if the bug is fixed, that is ;))

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.
