.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.
