Processes practice ps command not working properly

[tudorcondrea]

Hello, in the Processes subsection where we open 10 sleep processes, the ps -e -H -o pid,ppid,cmd | (head -1; grep "python3 sleepy_creator.py") and ps -e -H -o pid,ppid,cmd | (head -1; grep sleep) do not show the list of processes, however running ps -e -H is sufficient

Do the commands show any output? They should only show the PIDs, PPIDs and commands of the sleep processes. The point is not to view the whole process hierarchy.

[tudorcondrea]

They only show the table head and no processes at all, even though they are running

Stupid question, but did you implement the TODOs from sleepy_creator.py?

Can you try with the one in the solution directory and see if you have the same pattern?

ps -e -H -o pid,ppid,cmd | (head -1; grep "python3 sleepy_creator.py") and ps -e -H -o pid,ppid,cmd | (head -1; grep sleep) should show you only the sleep process, not all processes as ps -e -H does.

Any updates on this?
