This is not a "private" method.
Alot of nonsense to do an EXTREMELY simple task
This is just using standard linux commands in the Cygwin environment.
Its akin to installing a whole virtual machine so you can us its text editor ...retarded
using Cat and grep are in no way shape or form a private method. These are standard file manipulation commands
In windows this "private" method is as simple as
type file1.txt file2.txt > combined.txt
To search for specific stings in a bunch of files in a directory
findstr /SPIN "search_string" C:\some_directory\*.txt >> found.txt
no cygwin needed
Should get a refund for unveiling this crap lol
I just gave you the same information for FREE lol No HoH coins needed
