I was just curious why you would do this:
@files = reverse (sort { $files{$a} <=> $files{$b} } keys %files);
instead of this:
@files = sort { $files{$b} <=> $files{$a} } keys %files;
As for the "2A" example, you could simplify that to a single system call:
my $redirect = ( $TRACE < 2 ) ? '>' : '| tee'; system( "sed s/{author}.*//g <$file $redirect ${file}1.txt";
The trick there is that when you pipe to "tee filename", output is written to both stdout and to filename; and the stdout from "system()" is the same as the perl script's STDOUT, so you'll see it.

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.
