SYNOPSISpwconv [-P path]
DESCRIPTIONpwconv installs and updates /etc/shadow with information from
/etc/passwd. It relies on the special password 'x' in the password
field of the account. This value indicates that the password for the
user is already in /etc/shadow and should not be modified.
If /etc/shadow does not exist, pwconv creates this file, moves the user
password to it and creates default aging informations with the help of
the values of PASS_MIN_DAYS, PASS_MAX_DAYS and PASS_WARN_AGE from
/etc/login.defs. The password field in /etc/passwd is replaced with the
special character 'x'.
If the /etc/shadow does exist, entries that are in the /etc/passwd file
and not in the /etc/shadow file are added to the /etc/shadow file.
Accounts, which only exist in /etc/passwd, are added to /etc/shadow.
Entries that are in /etc/shadow and not in /etc/passwd are removed from
/etc/shadow. All passwords from /etc/passwd are moved to /etc/shadow
and replaced with the special character 'x'.
pwconv can be used for initial conversion and for updates later.
OPTIONS-P, --path path
The passwd and shadow files are located below the specified
directory path. pwconv will use this files, not /etc/passwd and
/etc/shadow.
