how can you kill a process in solaris 10 and confirm that it has been really killed (not hanging etc)

Use pd -ef to list the running processes and find the pid of the process that you want to kill

now execute the command

kill - 9 pid

where pid was found from ps -ef , now again check from ps -ef to confim that the process has been killed, this is same for all solaris nothing different for solaris 10
