User Id
 
Is user ID person who is in the current system?

fahrisal@linux:~> who am i

Is "fahrisal" a user ID?

how to identify whether the particular user has logged in (using shell script)?

It's a name, not an id. The uid is a numerical value.

To retrieve the name there's several possibilities.
Code:
a) the one you already listed `who am i`
b) echo $LOGNAME
c) `id` which will give you pretty much all you need to
  know about the user you're currently running the program
  id as ... :} (in terms of id and groups, that is).


Cheers,
Tink

check out 'man id', as Tinkster suggested.
