Topic: Incorrect commands
In the OpenRC section of the wiki, the command
# passwd -a <your-user> <some-group-name>
is used to
add your user to the group
.
This command is incorrect. According to the man page,
# passwd -a
can be used only with -S and causes show status for all users.
.
It does not in any way add your user to the group. In fact, used as shown in the wiki it only outputs the --help information for the passwd command, since that command only accepts two arguments, [OPTIONS] and [LOGIN].
Edit:
All references to the passwd command in this context should be changed to
# groupmems -a <your-user> -g <some-group-name>
.
