Thanks for all the help.

This works except I keep getting these error messages along with output:

Use of uninitialized value at per2.pl line 5.
Use of uninitialized value at per2.pl line 5.
Use of uninitialized value at per2.pl line 8.
Use of uninitialized value at per2.pl line 8.

Here is the script:

#!/usr/local/bin/perl -w

use strict;
my  ( @temp, %authors );
@temp = sort map { my @b=split; $b[2]; } `ls -l /directory/pth/here`;
foreach ( @temp )
{
   $authors{$_}=1 if not $authors{$_} and length $_; 
#I had to add $_ because the other way "$authors{$}=1" gave me an erro
+r
}
print "$_\n" for keys %authors;

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.
