Am reading through the Debian Administrator's guide for Jessie.
The following page seems to have incorrrect info:
https://debian-handbook.info/browse/sta ... bases.html
It talks about the commmand "passwd -g groupname" to change the password for a group.
There's no -g option in the passwd command. From googling and reading the man page, I found it's actually "gpasswd" by itself to put in a passwd for a group name.
Am I correct in this? How does one submit for correction?
