And the award for the crappiest man page goes to tccutil

At least it doesn't tell you it's deprecated. (:

    $ man whoami
    
    DESCRIPTION
         The whoami utility has been obsoleted by the id(1) utility, and is equiv-
         alent to ``id -un''.  The command ``id -p'' is suggested for normal
         interactive use.
