Playing with threads

[Ganesh Pal]

Hi friends,

I'm trying to use threads  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  found

Questions:

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

Regards,
Ganesh
