whoami − display effective current username

SYNOPSIS

whoami

DESCRIPTION

whoami displays the username of whoever is currently logged in.  whoami works even if you’ve used su to pick up another username, while ‘who am i’ does not since it gets its information from the  /etc/utmp file. 

In other words,

whoami shows who you are now, while

who am i shows who you where when you logged in.
