just going through chapter 7 of Mc Graw Hill study guide,

it says all about the ownership of a directory and file and there permissons for owner, gorup and other

How do you add a group and allow it a set of permissions?

    couldn't see my answer on there, can it be done or do you just need to add the user to the owning group?

    You use the chgrp command to set or change the group on a file.

    Then use the chmod -g to set whatever permissions that group has to the file (chmod -g+r+w for read and write for example).

    All things are possible, only believe.

    You asked how to add a group and allow it a set of permissions.

    The articles states

    groupadd GROUP

    to add a group, and to add permissions it also states

    "You can also use the chown command with the -r switch for it to doe recursive searches down into directories to change permissions. "

    yeah sorry my question was badly worded, i'll have another go


    You can edit permissions for owner, owner group and other. so lets say that I have a file that belongs to a group called 'mobile' and the permissions on the file are u=rw,g=rw,o=r, how can I have it so that another group called 'roomA' can have rw permissions without giving rw permissions to other?

    Take a look at

    setfacl

    That should do it for you. :) I don't want to give you the exact answer so you learn how it works on your own.
