Why is the parole(just a media palyer) still listed in the "JOBS" command output even after killing maually and why is not listed in the "PS" command output ?

  1. Does this mean the process is still runnig in background(ps:when i issued kill command the media playe[parole] is closed))?
  2. If running why is it not listed in the "PS" command output ? If not running what is the meaning of the output for "JOBS" command.

 134043 pts/4    00:00:00 ps

[1]+  Terminated              sleep 30
 > jobs

according to man bash, JOB CONTROL

The shell learns immediately whenever a job changes state. Normally, bash waits until it is about to print a prompt before reporting changes in a job's status so as to not interrupt any other output.

so you can even use an empty command (i.e. press return), to see the done line.

    Also, a job that is stopped cannot receive a signal (the default is sigterm, and it may have a handler installed). So after you kill it, it needs to run just to terminate and have the shell notice, to get its status from the process list. A process is like Schrodinger's cat -- it is not truly dead until it is observed to be dead. – Paul_Pedant Aug 4 '20 at 9:04
