Build cmd command to extract PID from tasklist and use condition on the result

Question

I'm trying to write one line cmd command that:

• execute tasklist with PID filter
• iterate over the output
  • do something if PID found
  • do something else if PID was not found

So I've read How to extract a specific field from output of tasklist on the windows command line and used this answer to construct this command:

for /f "tokens=2 delims=," %F in ('tasklist /nh /fi "PID eq 5284" /fo csv') do if %F NEQ "5284" (@echo no) else  (@echo yes)

I didn't get the expected result. Most likely got the syntax wrong.

Just posting the answer commented by eryksun:

(for /f "tokens=2 delims=," %F in ('tasklist /nh /fo csv /fi "PID eq 5284"') do @echo yes) || @echo no
