First write differences down. Then design subroutine arguments. Then desing subroutine. What are the differences?
  • List of field indexes.
  • grep regexp (NETPACKET, NETERROR)
  • grep regexp (Network, Busy, Memory)
  • what to do with arguments?
  • others?
Then subroutine arguments:
sub yoursub { my ($rangearrayref, $firstre, $secondre, $subref) = @_; ... } yoursub([2..7], 'NETPACKET', 'Network', \&transformNetpacketSub);
or hash style:
sub yoursub { my %args = @_; my ($rangearrayref, $firstre, $secondre, $subref) = ($args{-range}, +$args{-firstre}, $args{-secondre}, $args{-transformsub}); ... } yoursub(-range => [2..7], -firstre=>'NETPACKET', -secondre=>'Network', + ->transformsub=>\&transformNetpacketSub);
And then the only problem is to write proper transformNetpacketSub. I would do it like this:
sub transformNetpacketSub { my $str = shift; # do anything with string return $str; }

Title:
Use:  <p> text here (a paragraph) </p>

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.
