None of those three "statements" make sense to me. Could you translate, 
or elaborate? And fix typos?
What OS is this running on?
Is the process a program called grep.exe? Or a second Python program? 
Who's doing the grep, that separate program or your original one?
Define Apply. What's it mean to apply a string to a command?
What's an "is pattern" ? And who's looking for it?
What's the real goal? Or is this just a paraphrasing of an arbitrary 
school assignment (which don't always make sense).

Sure, nothing in that description implies threads, just a separate 
process. No idea why that's simpler, though.
