NAME

pwconv − installs and updates /etc/shadow with information from /etc/passwd

SYNOPSIS

pwconv

AVAILABILITY

SUNWcsu

DESCRIPTION

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

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.
