You don't need to be a Guru to do such kind of work!

I propose the following approach

• open the file
• read the file line by line
  • if the line contains one of your keywords, just increase a counter related to it
  • (you can identify the keyword with a simple regex (e.g. if ($line =~ /RequestREGISTER/) { $regcnt++; }) - simple, isn't it?)

To process the number or unique TIDs, remember the wise words of brother brian_d_foy in perlfaq4:

Use a hash. When you think the words "unique" or "duplicated", think "hash keys".

So extract the TID from your line (again using a regex), add them to a hash, and process the hash as you wish once you finished reading the file.

HTH, Rata
