NAME
     whoami - display the effective current username

SYNOPSIS
     /usr/bin/whoami

DESCRIPTION
     whoami displays the login name corresponding to the current effective
     user ID.  If you have used su to temporarily adopt another user, whoami
     will report the login name associated with that user ID.  whoami gets its
     information from the geteuid and getpwuid library routines (see getuid
     and getpwent, respectively).

FILES
     /etc/passwd         username data base

SEE ALSO
     su(1), who(1), getuid(2), getpwent(3)

NOTES
     The whoami command provided in versions of IRIX prior to 5.0 was a
     symbolic link to /usr/bin/id(1).
