LOGNAME(1)                   BSD Reference Manual                   LOGNAME(1)

NAME
     logname - display user's login name

SYNOPSIS
     logname

DESCRIPTION
     The logname utility writes the user's login name to standard output fol-
     lowed by a newline.

     The logname utility explicitly ignores the LOGNAME and USER environment
     variables because the environment cannot be trusted.

     The logname utility exits 0 on success, and >0 if an error occurs.

SEE ALSO
     who(1),  whoami(1),  getlogin(3)

STANDARDS
     The logname function is expected to conform to IEEE Std1003.2
     (``POSIX'').

HISTORY
     The logname command appears in 4.4BSD.
