.SH "DESCRIZIONE"
|
|
.PP
|
|
The
|
|
\fBchgpasswd\fR
|
|
command reads a list of group name and password pairs from standard input and uses this information to update a set of existing groups\&. Each line is of the format:
|
|
.PP
|
|
\fIgroup_name\fR:\fIpassword\fR
|
|
.PP
|
|
By default the supplied password must be in clear\-text, and is encrypted by
|
|
\fBchgpasswd\fR\&.
|
|
.PP
|
|
The default encryption algorithm can be defined for the system with the
|
|
\fBENCRYPT_METHOD\fR
|
|
variable of
|
|
/etc/login\&.defs, and can be overwritten with the
|
|
\fB\-e\fR,
|
|
\fB\-m\fR, or
|
|
\fB\-c\fR
|
|
options\&.
