When I execute ps ax command with grep, it' showing a single entry of test.py

test.py was just single print statement submitted like this: 

nohup python test.py &

So I'm assuming it didn't take long to run. Should that entry still be there? 

$ ps ax | grep test.py
18225 pts/0    S+     0:00 grep test.py

    Your `ps` is showing the `grep` process that's filtering the `ps` output for `test.py`, not a `python` process running the thing... – Andy Dalton May 23 '20 at 19:47
  • How can I tell the difference between a running process that was found with grep versus the filtering? – Rod May 23 '20 at 19:51
  • _How can I tell the difference..._ One will say `grep`, the other will say `python`. See the above suggested link re `grep -v grep` – Andy Dalton May 23 '20 at 23:14
