  15.      The _pppp_wwww_cccc_oooo_nnnn_vvvv command creates and updates _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww with information from
  16.      _////_eeee_tttt_cccc_////_pppp_aaaa_ssss_ssss_wwww_dddd.
  17.  
  18.      If the _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww file does not exist, _pppp_wwww_cccc_oooo_nnnn_vvvv creates _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww with
  19.      information from _////_eeee_tttt_cccc_////_pppp_aaaa_ssss_ssss_wwww_dddd.  The command populates _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww with the
  20.      user's login name, password, and password aging information.  If password
  21.      aging information does not exist in _////_eeee_tttt_cccc_////_pppp_aaaa_ssss_ssss_wwww_dddd for a given user, none is
  22.      added to _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww.  However, the last changed information is always
  23.      updated.
  24.  
  25.      If the _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww file does exist, the following tasks are performed:
  26.  
  27.      +o  Entries that are in the _////_eeee_tttt_cccc_////_pppp_aaaa_ssss_ssss_wwww_dddd file and not in the _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww
  28.         file are added to the _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww file.
  29.  
  30.      +o  Entries that are in the _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww file and not in the _////_eeee_tttt_cccc_////_pppp_aaaa_ssss_ssss_wwww_dddd
  31.         file are removed from _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww.
  32.  
  33.      +o  Password attributes (for example, password and aging information) in
  34.         an _////_eeee_tttt_cccc_////_pppp_aaaa_ssss_ssss_wwww_dddd entry are moved to the corresponding entry in
  35.         _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww.
  36.  
  37.      The _pppp_wwww_cccc_oooo_nnnn_vvvv program is a privileged system command that cannot be executed
  38.      by ordinary users.
  39.  
  40.      The contents of the _////_eeee_tttt_cccc_////_pppp_aaaa_ssss_ssss_wwww_dddd and _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww files are saved in
  41.      _////_eeee_tttt_cccc_////_oooo_pppp_aaaa_ssss_ssss_wwww_dddd and _////_eeee_tttt_cccc_////_oooo_ssss_hhhh_aaaa_dddd_oooo_wwww, respectively.  The system can be restored
  42.      to its preconversion state by replacing the content of the _////_eeee_tttt_cccc_////_pppp_aaaa_ssss_ssss_wwww_dddd
  43.      file with the content of _////_eeee_tttt_cccc_////_oooo_pppp_aaaa_ssss_ssss_wwww_dddd and removal of _////_eeee_tttt_cccc_////_ssss_hhhh_aaaa_dddd_oooo_wwww (if it
  44.      did not exist prior to the run of _pppp_wwww_cccc_oooo_nnnn_vvvv) or its replacement by
  45.      _////_eeee_tttt_cccc_////_oooo_ssss_hhhh_aaaa_dddd_oooo_wwww.  These files are overwritten each time the _pppp_wwww_cccc_oooo_nnnn_vvvv program
  46.      is run.  The use of some of the system administration tools causes _pppp_wwww_cccc_oooo_nnnn_vvvv
  47.      to be run, and therefore the backup files to be overwritten, each time an
  48.      entry is added, deleted, or modified.

  51.      _p_w_c_o_n_v does not copy NIS entries from _////_eeee_tttt_cccc_////_pppp_aaaa_ssss_ssss_wwww_dddd. However, a shadow file
  52.      can be served by NIS using nsd (see sssshhhhaaaaddddoooowwww((((4444))))).
