.TH PWCONV 8
.SH NAME
pwconv \- convert and update shadow password files
.SH SYNOPSIS
.B pwconv
.SH DESCRIPTION
\fBPwconv\fR copies the password file information from \fI/etc/passwd\fR
to the shadow password file, \fI/etc/shadow\fR.
If the \fI/etc/shadow\fR file does not exist, it is created with
modes which only permit read access to the owner.
Shadow entries in the System V Release 3.2 format will be silently
converted to the new System V Release 4 format.
Any entries which are missing fields will have those fields
filled in with default values where appropriate.
New entries are created with passwords which expire in 10000 days,
with a last changed date of today,
unless password aging information was already present.
Shadow entries without corresponding entries in \fI/etc/passwd\fR
are removed.
