This might sound like a strange one, but I need to have all the errors that display in the CGI interface of my program to NOT have the script name or line numbers. For example, I'm using CGI::Carp to intercept any fatal errors: 
use strict;
use CGI::Carp qw/fatalsToBrowser set_message/;

BEGIN {
  sub die_nice { # this will intercept any fatals
    my $err = shift;
    print "<html>\n<body>\n<h1>Custom CGI Error</h1>\n";
    print "<pre>$err</pre>\n";
    print "[script-specific error/dump info goes here]\n";
    print "</body>\n</html>\n";
    warningsToBrowser(1);
  }
  set_message(\&die_nice);
}

die('[this is the message passed to die]');

Now, running this code would (more or less) produce this in my browser: 
[this is the message passed to die] at /home/evan/dietest.cgi line 18.

The thing is, once I put it into production, I'd only want the users to see [this is the message passed to die] while the full error would still appear in the apache error log. the only way I can think of doing this is to filter the error message like so: 
sub die_nice {
  my $err = shift;
  $err =~ s/ at \S+ line \d+//g
  
  print "<html>\n<body>\n<h1>Custom CGI Error</h1>\n";
  print "<pre>$err</pre>\n";
  print "[script-specific error/dump info goes here]\n";
  print "</body>\n</html>\n";
  warningsToBrowser(1);
}

This will work, mind you (im using it right now), but it seems like a hacky solution, plus what if the regex matches some other part of a strangely worded error...is there a Better Way™?
