Well, "who am i" is just a synonym for "id -un" (as stated by "who --help")
on cygwin; here it only prints the current user name;
$ who am i
Hannu tty0 Apr 21 20:47 (:0)
$ who
Hannu tty0 Apr 21 20:47 (:0)
$ whoami
Hannu
The ipconfig stuff isn't much more reliable, depending on your setup.
I always have TWO IP's when my PPP/ISDN is up:
$ ipconfig /all
