Is there an alternative to "whoami" ?

But watch out, they can return different results, an example:
----------
me@trout:/home/me $ su -
Password:
Sun Microsystems Inc. SunOS 5.10 Generic January 2005
root@trout:/root # who am i
me pts/1 Jun 30 17:27 (cod.mydom.net)
root@trout:/root # whoami
root
root@trout:/root #
--------------
'who am i' returns who you logged in as, where as '/usr/ucb/whoami' returns
your effective ID, not always the same either.
It is best to add ucb to your search path:
PATH=$PATH:/usr/ucb:/usr/sfw/bin:/usr/ccs/bin
export PATH

Not! His next question then will be why cc doesn't work.
Worse, if /usr/ucb is not *last* in the $PATH ps will not work as expected
either.

Yep:
/usr/xpg4/bin/id -un
rich@zen4153# /usr/xpg4/bin/id -un

Not it is NOT! /usr/ucb is an anacronism, best forgotten in this
day and age.

One might try using aliases for /usr/ucb stuff and /usr/xpg? stuff
Keeps PATH clean

Or, if running Nevada or OpenSolaris, just have /usr/gnu/bin in the $PATH.
Heh!, that's not even necessary:
duhring@einstein:~$ which whoami
/usr/bin/whoami
usenetper...@gmail.com
I havent checked my b90 install for /usr/ucb - hope they dont do away
with it but who knows.
Thing is, a GNU version of something isnt always "better" than the
original.
Is there a vipw for example? Probably not. /usr/ucb/shutdown can get
you
out of some jams that the svr4 descendant cannot. /usr/ucb is small
sans
all the symlinks. I hope it survives the current wave of
"we gotta make Solaris more Lienux friendly" types developing at Sun
nowadays : >

It is still there in b91, as is /usr/ucblib and /usr/ucbinclude.

With Sun's promise of backward compatibility /usr/ucb and cousins will
probably remain for some time to come.

Granted, but sometimes the GNU versions do have additional or different
utility. Additionally, the presence of such penguinware eases the
transition for Linux emigrés.

The -r option in GNU's grep is quite handy, for instance.
