file & dir permissions
 

Hello, First Post! WOW!

Trying to change persmissions for one user group. Enable permission so they CANNOT access any other file & directories other than their own ones belonging in their group. So they can access all 'accounts'(group) files & dirs but no other groups files & dirs 'sales' or 'IT'.

Working with commands CHGRP & CHOWN, but confused

ty, lnxDE

also you use chmod to change the permissions of dirs/files..

man chmod
for all the details

Hi lnxDE,

You can 'man' any command that you know (well most anyway) but the man pages ARE confusing when you are fisrt starting out, so with this in mind I'll outline a few things to help you on your way...

first thing is to set the group access to the files... lets work with /usr/local/share as an example. Set the group users as the group for this directory,

chgrp users /usr/local/share

Thats pretty easy. Now you want to allow folks in the group users (and the owner) to have full permissions to access the folder but noone else...

chmod 770 /usr/local/share

you may want users to only read and execute things in this directory (owner has full access...

chmod 750 /usr/local/share

basically the easiest way to set file permissions is using the chmod command with binary input.

so 750 gives the permissions drwxr-x--- to the above dir.

0 gives --- 1 gives --x 2 gives -w- 3 gives -wx 4 gives r--
5 gives r-x 6 gives rw- 7 gives rwx

and the location of the values is also important...

chmod 750 here the 7 is set for the owner of the file or dir. the 5 sets r-x for the group, and 0 is set for the oranisation or anyone who can access the filesystem.

Thats it in a nutshell, there is alot more to chmod but this will get you well under way.
