Hi, try this,
use strict;
my $arg = $ARGV[0];
open(IN,"$arg")||die("Can't open the input file for reading");
undef $/;
my $str = <IN>;
close(IN);
$str=~s#\$[^\$]+\$#&LimitReplace($&)#gei;
open(OUT,">$arg")||die("Can't open the output file for writing");
print OUT $str;
close(OUT);
sub LimitReplace{
my ($line)=@_;
$line=~s#\\limits##gi;
return($line);
}

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).

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