NAME
       ac - login accounting

SYNOPSIS
       /etc/ac [ -w wtmp ] [ -p ] [ -d ] [ people ] ...

DESCRIPTION
       _A_c produces a printout giving connect time for each user who has logged
       in during the life of the current _w_t_m_p file.  A total is also produced.
       -w  is  used  to  specify an alternate _w_t_m_p file.  -p prints individual
       totals; without this option, only totals  are  printed.   -d  causes  a
       printout  for  each midnight to midnight period.  Any _p_e_o_p_l_e will limit
       the printout to only the specified login names.  If  no  _w_t_m_p  file  is
       given, _/_u_s_r_/_a_d_m_/_w_t_m_p is used.

       The  accounting  file  _/_u_s_r_/_a_d_m_/_w_t_m_p  is  maintained by _i_n_i_t and _l_o_g_i_n_.
       Neither of these programs creates the file, so if it does not exist  no
       connect-time  accounting  is  done.   To start accounting, it should be
       created with length 0.  On the other hand if the file  is  left  undis‐
       turbed  it  will  grow  without  bound, so periodically any information
       desired should be collected and the file truncated.
