NAME

pwconv - convert to shadow account

SYNOPSIS

pwconv [-P path]

DESCRIPTION

pwconv installs and updates /etc/shadow with informationfrom /etc/passwd. It relies on the special password 'x' in thepassword field of the account. This value indicates that the passwordfor 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 informationswith the help of the values of PASS_MIN_DAYS, PASS_MAX_DAYSand PASS_WARN_AGE from /etc/login.defs. The password fieldin /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 areadded to the /etc/shadow file. Accounts, which only exist in/etc/passwd, are added to /etc/shadow. Entries thatare in /etc/shadow and not in /etc/passwd are removedfrom /etc/shadow. All passwords from /etc/passwd aremoved to /etc/shadow and replaced with the special character 'x'.

pwconv can be used for initial conversion and for updates later.
