At 16:45 - grep -v PID will return everything except the PID as thats the behaviour of -v option. I think it should be just grep PID?

[@DGRUploads]

Thank you for the query. I can confirm that the command is working as expected. I have tested it on my machine and it gives the right output.
Example output from the command :
ubuntu@ip-172-31-29-161:~$ ps -u ubuntu | grep -v PID | awk '{print $1}'
