HOw to identify Unix process owned by a user

 

  

Hi All,

Is there any way to find out the processes that i as a user have
specifically initiated .
I have logged into Unix os as abc/abc user.
and have issued some unix commands.Like
ps -wef
ls
sqlplus username/passwd
.
.
.
.
.
.

Another user also has logged in using same username and password i.e
abc/abc
and also issues the same command
sqlplus username/password
ps -wef
ls
.
.
.


How do i identify/differentiate wat commands i have issued and what all
commands other has issued when both of us has logged in as same user.

Any idea would e of great help

TIA
-Parul
