     from /etc/passwd

     The pwconv command  creates  and  updates  /etc/shadow  with
     information from /etc/passwd.

     pwconv relies on a special value  of  'x'  in  the  password
     field  of /etc/passwd.  This value of 'x' indicates that the
     password for the user is already in /etc/shadow  and  should
     not be modified.

     If the /etc/shadow file does not exist,  this  command  will
     create  /etc/shadow  with information from /etc/passwd.  The
     command populates /etc/shadow with the  user's  login  name,
     password, and password aging information.  If password aging
     information does not exist in /etc/passwd for a given  user,
     none  will  be  added  to  /etc/shadow.   However,  the last
     changed information will always be updated.

     If the /etc/shadow file does exist, the following tasks will
     be performed:

          Entries that are in the /etc/passwd file and not in the
          /etc/shadow file will be added to the /etc/shadow file.

          Entries that are in the /etc/shadow file and not in the
          /etc/passwd file will be removed from /etc/shadow.

          Password attributes (for example,  password  and  aging
          information) that exist in an /etc/passwd entry will be
          moved to the corresponding entry in /etc/shadow.

     The pwconv command can only be used by the super-user.

     /etc/passwd
