How do i know my currently logged on userid in Solaris/Unix
 

Hi

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.

Thanks.

Try "whoami" rather than "who am i".

The first displays the effective user, the latter is an invocation of "who" (that displays logged on users, etc - see man who) and is equivalent to "who -m".

apparently it is not working

i am using solaris

who - m will still give me username i logged on first time using putty
there is no whoami command in Solaris


any idea?
thanks

Actually this BSD command is supported by Solaris:
/usr/ucb/whoami
and so is its System V equivalent:
/usr/bin/id
