       This manual page documents the GNU  version  of	wwhhoo.   If
       given  no  non-option  arguments, wwhhoo prints the following
       information for each user currently logged on:

	      login name
	      terminal line
	      login time
	      remote hostname or X display

       If given one non-option argument, wwhhoo uses that instead of
       /etc/utmp as the name of the file containing the record of
       users logged on.	/etc/wtmp is commonly given as an  argu-
       ment to wwhhoo to look at who has previously logged on.

       If  given  two  non-option  arguments, wwhhoo prints only the
       entry for the user running it (determined from  its  stan-
       dard input), preceded by the hostname.  Traditionally, the
       two arguments given are `am i', as in `who am i'.

   OOPPTTIIOONNSS
       _-_m     Same as `who am i'.

       _-_q_, _-_-_c_o_u_n_t
	      Print only the login names and the number of  users
	      logged on.  Overrides all other options.

       _-_s     Ignored;	for  compatibility with other versions of
	      wwhhoo.

       _-_i_, _-_u_, _-_-_i_d_l_e
	      After the login time, print the number of hours and
	      minutes that the user has been idle.  `.' means the
	      user was active in last minute.	`old'  means  the
	      user was idle for more than 24 hours.

       _-_H_, _-_-_h_e_a_d_i_n_g
	      Print a line of column headings.

       _-_w_, _-_T_, _-_-_m_e_s_g_, _-_-_m_e_s_s_a_g_e_, _-_-_w_r_i_t_a_b_l_e
	      Like  _-_s, plus after the login name print a charac-
	      ter indicating the user's message status:

	      +	allowing wwrriittee messages

	      -	disallowing wwrriittee messages

       The long-named options can be introduced with `+' as  well
       as  `--', for compatibility with previous releases.  Even-
       tually support for `+' will  be	removed,  because  it  is
       incompatible with the POSIX.2 standard.
