And the last question should have been:

Can I say what processes are running in the background (only the last one run is in $apid) and is it possible to get them back to foreground?

Hello,

is there any simple way how to identify processes belonging to one concrete process group?

Is there any simple way how to change a process' group?

Is there anything like pstree in plan9?

Thanks
