There are a few shortcuts that could make this smaller, but the code below is one way to comment lines that matched a list of words.

However, you will probably need to dial in the regex to better meet your needs.

#!/usr/bin/perl use strict; use warnings; my @file_a_array; my $newfile; my $file_a = <path to word file>; my $file_b = <path to lines of text>; open (FILE_A, "$file_a") or die "couldn't open the file!"; while (my $line = <FILE_A>) { chomp ($line); push (@file_a_array, $line); } close (FILE_A); open (FILE_B, "$file_b") or die "couldn't open the file!"; while (my $line = <FILE_B>) { chomp ($line); foreach my $word (@file_a_array) { if ($line =~ /$word/) { $newfile = $newfile . "# "; } } $newfile = $newfile . $line . "\n"; } close (FILE_B); open (FILE_B, ">$file_b") or die "couldn't open the file!"; print FILE_B $newfile; close (FILE_B); print "end\n";

Hope this helps!

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 How to display code and escape characters are good places to start.
