+.PP
+The

+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
+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
