thanks RTM.. the corrected version is as belows

i log in as root and is in pts/11 , do a who -uH, got the below

root pts/11 Dec 11 08:01 0:10 11588
root pts/12 Dec 11 09:09 0:03 12001

now do a ps -ef | grep pts/12, get the below

**** CHANGED THE BELOW TWO LINES ****
root 12133 12107 0 09:18:22 pts/12 0:00 vi myoracle
root 12107 12105 0 09:14:48 pts/12 0:00 -csh

1) so now i am in pts/11, but i want to kill the process at pts/12 which is "vi myoracle". How?

2) are pts/11, pts/12 called as terminals?

3) rtm, I wanted to get back to that session but it gets hanged... and therefore the though of killing it from other pts...

4) will take a man look and hopefully will provide a answer.
