You ask good questions. Disregard my earlier code because it was using the wrong variable to search with (I think that's correct?)

What I am wanting is to find out how many times the long "exe" strings appear in a file. Then print each result with a name for the string rather than the string itself. Eg:

C:\Program Files\Internet Explorer\IEXPLORE.EXE
[download]

in:

3/15/2004,2:29:31 PM,Security,Success Audit,Object Access ,560,SERVER\
+refterm,SERVER,"Object Open:
     Object Server:    Security
     Object Type:    File
     Object Name:    C:\Program Files\Internet Explorer\IEXPLORE.EXE
     New Handle ID:    548
     Operation ID:    {0,178005108}
[download]

Result:

Name: Explorer  Count: 1
[download]

It seems I was walking down the wrong path and will have to use regex (which I have not yet read about, in all honesty) to search for the exe string within each line of text. The 'crime', 'crimean' issue is not a problem because there are no variants of the strings I'd be counting. There are MANY paragraphs like the one above in the file to be searched.

If you have any ideas what this code might look like feel free to offer it :-) I will learn as much on my own in the meantime!

It seems I ... will have to use regex

This is not correct. Regexes are for cases where you don't know what to search for exactly, you just now how the pattern looks like, e.g. two letters followed by 3 or more digits ending with a newline. In your case, you are searching for a literal string and thus you can use index (see perldoc -f index).

Assuming that the long filenames are not broken across lines and the same filename does not appear multiple times on on line, the following should do what you want:

use strict;

@ARGV = ('security.txt') unless @ARGV;
my %exe = (
  'C:\Program Files\Internet Explorer\IEXPLORE.EXE' => 'Catalog',
  'D:\crime\Reader\AcroRd32.exe' => 'Crime',
);

my %count;
while (<>) {
   for my $filename (keys %exe) {
     %count{ $exe{filename} }++
       if index($_, $filename) > -1;
   };
}

print "Name: $_ Count: $count{$_}" for keys %count;

The trick is to define the hash %exe the other way around, so that it gives the short name when accessed with the long filename.
