pwconv - installs and updates /etc/shadow with information
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
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.
