Use the pstree command to list processes in a tree format. It will show the process owners. Default is to start the root of the tree at init:
u-1@srv-1 u-1 $ pstree init-+-3*[agetty] |-ahc_dv_0 |-bdflush |-crond---2*[sh---perl---sh-+-grep] | `-iget-quote] |-cupsd |-devfsd |-keventd |-khubd |-kjournald |-kscand |-ksoftirqd_CPU0 |-kswapd |-kupdated |-lockd |-login---bash---startx---xinit-+-X | `-sh-+-icewm-+-Eterm---bash---ssh | | |-Eterm---bash---pstree | | |-mozilla-bin---mozilla-bin--+ | | `-xmms---xmms---2*[xmms] | `-xscreensaver |-login---bash---ssh |-login---bash---perl |-metalog---metalog |-portmap |-rpciod `-scsi_eh_0 u-1@srv-1 u-1 $ |
