I assume you mean "who am i" - my SysV machines don't have whoami.  This
has been the case for at least SysVr2.0 ->3.2.  I reported it a long time
ago.  One possible workaround (the one I used..) is to use the environment
variable LOGNAME instead, although that is less secure.  Or just make all
your login id's less than 8 characters long.
A related problem with the longer names is that mail to names which match
the 1st 8 characters of a login name is accepted and stored even though
the name differs past the 8th character.  For example, if you have
"longname" as a login id, mail to "longname5" will land in /usr/mail/longname5
instead of being rejected.
