.TH PWCONV 1M "Mar 9, 1993"
.SH NAME
pwconv \- installs and updates /etc/shadow with information from /etc/passwd
.SH SYNOPSIS
.LP
.nf
\fBpwconv\fR
.fi
.SH DESCRIPTION
.sp
.LP
The \fBpwconv\fR command creates and updates \fB/etc/shadow\fR with information
from \fB/etc/passwd\fR.
.sp
.LP
\fBpwconv\fR relies on a special value of 'x' in the password field of
\fB/etc/passwd.\fR This value of 'x' indicates that the password for the user
is already in \fB/etc/shadow\fR and should not be modified.
.sp
.LP
If the \fB/etc/shadow\fR file does not exist, this command will create
\fB/etc/shadow\fR with information from \fB/etc/passwd\fR. The command
populates \fB/etc/shadow\fR with the user's login name, password, and password
aging information. If password aging information does not exist in
\fB/etc/passwd\fR for a given user, none will be added to \fB/etc/shadow\fR.
However, the last changed information will always be updated.
.sp
.LP
If the \fB/etc/shadow\fR file does exist, the following tasks will be
performed:
.sp
.ne 2
.na
\fB\fR
.ad
.sp .6
.RS 4n
Entries that are in the \fB/etc/passwd\fR file and not in the
\fB/etc/shadow\fR file will be added to the \fB/etc/shadow\fR file.
.RE
.sp
.ne 2
.na
\fB\fR
.ad
.sp .6
.RS 4n
Entries that are in the \fB/etc/shadow\fR file and not in the
\fB/etc/passwd\fR file will be removed from \fB/etc/shadow\fR.
.RE
.sp
.ne 2
.na
\fB\fR
.ad
.sp .6
.RS 4n
Password attributes (for example, password and aging information) that exist
in an \fB/etc/passwd\fR entry will be moved to the corresponding entry in
\fB/etc/shadow\fR.
.RE
.sp
.LP
The \fBpwconv\fR command can only be used by the super-user.
