Explained beautifully

[@AdvaTced]

note that it's not always adopted by the main process( PID 1 ) sometimes it get adopted by some PID that is the PID of the user ( that eventually part of the PID 1 obviously ).

You are very good. ❤

Thanks Amara. Glad to help

what a cool explanation

[@iradufashaBikri]

- > The unit process adopt the orphan.
-> After the orphan finish executing, unit process collect exit statuses of orphaned processes.
-> Unit process removes the orphan from the process table.
----------Zombie process---------
- If a parent process does not promptly collect the exit status of its terminated child using wait() or waitpid(), the child process becomes a zombie process.
- A zombie process still has an entry in the process table, but it does not consume system resources. It remains in the process table until the parent collects its exit status.
- Once the parent collects the exit status, the zombie process is removed from the process table.

Thanks Jesse

in my case the parent process died and the child process was adopted by 1333 which appears to be the systemd program. This fork systemcall was difficult yet amazing.

Thanks man.💯

Tnx Jesse

Youre welcome bro

I was thinking you would use getppid to get the PPID, because using getpid will return the PID of the current process, or do they all work the same?

[@abdulshahididal793]

From Timestamp 9:19, I think it should be "getppid()" for the PPID (Parent Process IDentifier) not "getpid()" because "getpid" is for PID (Process IDentifier). Thanks for the help. Appreciate!!

[@jess-inspired]

Hello Abdulshahid. You do have a point. Howbeit I used getpid() in the parent block because the pid of the parent is the ppid of the child..
getppid() would sure have been more appropriate if I used it in the child block..
Thanks for your observation though, much appreciated. .

[@shaheed007]

@@jess-inspired it was actually at 8:33 timestamp mark. Thanks though!

[@Sameh_ElGazar]

so , u are explaining the orphan not zombies?!

[@jess-inspired]

Yeah, although I did slightly touch on the zombie here.. Mixed up the names previously.. Apologise for whatever confusion it may have caused
