How do i know my currently logged on userid in Solaris/Unix
Lets say i telnet using putty to my server
i logged in as normal ( lets say "guest" )
then i type "who am i"
This one works nice i know guest is logged on
but there is a problem
after i logged on as guest
i do "su - oracle" for example and provide correct password
how do i know that my "guest" userid already changed to "oracle"
i type who am i still "guest" is showing up.
