If we want to kill a process first we have to know the
process id. We cam come to know ps or top command.
Then we have to identify the respective proce's child
process with the help of ptree command. Then we can give
kill id-1 id-2

example:- Take an example while using ps command

# ps
PID TT S TIME COMMAND
2243 pts/16 S 0:00 -csh

now we identified the PID no (2243) with the help of above
said ps command.

Then we have to give following command to know child
process_-

ptree 2243

1498 /usr/local/sbin/sshd
2062 /usr/local/sbin/sshd
2199 /usr/local/sbin/sshd
2205 -csh
2243 -csh
11535 ptree 2243

Now we can kill above said all ids.

kill 1498 2062 2199 2205 2243 11535
