in reply to (solaris) pbrun and the real user id

AFAIK su always changes both the real and effective UID (it did in my tests). Perhaps if you explain exactly what you're trying to do, we can come up with another way to do it.

    Actually, it depends on the implementation of su. I ended up using the who am i approach but it isn't full proof.

    sub whoami {
        return (split /\s+/, `/bin/who am i`)[0];
}
