20.3 ‘whoami’: Print effective user ID
======================================

‘whoami’ prints the user name associated with the current effective user
ID.  It is equivalent to the command ‘id -un’.

   The only options are ‘--help’ and ‘--version’.  Note: Common
options.

   An exit status of zero indicates success, and a nonzero value
indicates failure.
