NAME
       pwconv  -  installs  and	 updates  /etc/shadow  with  information  from
       /etc/passwd

SYNOPSIS
       pwconv

DESCRIPTION
       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.  How‐
       ever, the last changed information will always be updated.

       If the  /etc/shadow file does exist, the following tasks will  be  per‐
       formed:

	   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 correspond‐
	   ing entry in /etc/shadow.

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