I have a text file (file.txt) having content something like:
foo1 3464 foo2 3696 foo3 4562
It contains the process and respective PID.
Using shell script, I want to append a string (running/not running) to that lines in this file, according to the PID.
For example, in the above file, for line containing PID 3696, I want to append a string "running" at the end, so that the file becomes:
foo1 3464 foo2 3696 running foo3 4562
How can i do it?
