How to display authenticated username on linux?

Hi,

I'm trying to figure out how to diplay the currently authenticated username
on a linux machine. I am setting up a bunch of linux boxes, and they all
initially use the same user name. When a programmer gets a linux box, I
will have them do a "svn ls" command with the "--username" option to make
sure their username is cached. In order for them to check who's name is
cached, I would like them to enter a command that will display who's
username is the default subversion username. Currently the only way to
check is to display the svn.simple file like this:

     cat /home/username/.subversion/auth/svn.simple

Is there a more elegant way? Something line "svn whoami" ?

thx!
