Hi friends,

I'm trying to use threads=C2=A0 to achieve the below work flow

1. Start a process , while its running grep for a string 1
2. Apply the string 1 to the command in step 1 and exit step 2
3. Monitor the stdout of step1 and print success if the is pattern=C2=A0 fo= und

Questions:

1. Can the above be achieved without threads ? I prefer keep ing code
simple=C2=A0 .threads can become confusion when this workflow grows larger<= br>

I do not understand the work flow either.=C2=A0 What I do know is that Idle= Edit -> Find in Files is implemented in idlelib/grep.py and that the no= n-gui code could be copied and adapted to other purposes.
