logname(1)                BSD General Commands 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(2)


STANDARDS

     The logname utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
