whoami should return a user id that is assigned to the UID that you are
running under. If you are using the default OMVS User Id (Which must be
changed for z/OS V2.1) or a shared UID, then you will get any UID sharing
that UID returned.
who { and options } ; eg; who am i - can display additional information
about the user. By default, who display information about user's login
name, terminal name and time logged in. Note who am only works in the
POSIX locale
id will return the uid(username) gid(groupname). Again, if sharing uid
then any uid having that value can be returned.
logname will return the login name which is obtain via getlogin()
function.
Just for some additional notes, this is what I always do so that I always
know who I am and where I am at in OMVS...........
in /etc/profile I make sure logname is readonly so it can not be
changed......
readonly LOGNAME
set my command prompt to System Name:Log name:Directory
PS1='$System_Name':'$LOGNAME':'$PWD':'===>
export PS1

Interesting thread. From my strictly application-programmer level TSO
userid (the only one I have), entering those commands from TSO OMVS yields
the following results:
$ who am i
$ whoami
TSOUSER
$ id
uid=6101(TSOUSER) gid=60(OAPLGRP)
$ logname
FSUM6764 logname: cannot get login name
$
(Real userid was replaced by TSOUSER). No results at all from "who am I"
and a failure from "logname".
I suspect but cannot prove that system-programmer authority levels
probably produce distinctly different results.

LOGNAME command gives my RACF ID . Then what is the use of ID and WHOAMI
command. Why these command is working for some of them and for others not.
