pwunconv — convert passwords from shadow to nonshadow




The pwunconv command transfers the password and aging information for all users from /etc/shadow to /etc/passwd. The /etc/shadow file is removed.

Some of the aging information may be lost during the conversion; the warn and expire fields are discarded, while min, max, and lstchg are rounded from days to weeks.


HP recommends that you run pwck before running pwunconv. See pwck(1M).
