pwconv

pwconv(1M)                                                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  corre-
                sponding entry in  /etc/shadow.

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

FILES

DIAGNOSTICS
