System Administration Commands                         pwconv(1M)



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. 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.
