Here are the winning holes from the recent nigh-week-long golf competition on the "Fun With Perl" mailing list:

1. Print the first 10 lines of a file.

   #!/usr/bin/perl -p
   11..exit
   [download]

2. Print the last 10 lines of a file.

   #!/usr/bin/perl
   print+(<>)[-10..-1]
   [download]

3. Print a file in reverse.

   #!/usr/bin/perl -p
   $\=$_.$\}{
   [download]

4. Print the middle line (or two) of a file.

   #!/usr/bin/perl -p0
   $_=$1while/.^(.+)^/sm
   [download]

5. Print the line count of a file, zero-padded, right-aligned.

   #!/usr/bin/perl
   printf"%010d\n",$.,<>
   [download]

These are the shortest (or one of those shortest) for each of the five holes. A full list of entries can be found at my web site, and at http://archive.develooper.com/fwp@perl.org/.

• 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.
