changing root directory of a user
 

do to change the root directory of a user

do you mean swicthing directory?
to do that just type: cd /directory/ you want switch to or cd.. or if u mean changing user, type su user-name it should work.

Can you be more specific? It's not real clear what you are trying to do. Are you wanting to use a different folder instead of /home/username?

To change the root directory you use chroot. If that's truly what you meant, which I am not sure.

Can you give a clear reason why you want to use something other than "/home/userid" for a user's home directory?

Hi,

You should look at 'How to Ask Questions the Smart Way' to get the response you expect. As you can see the lack of information will get you varied replies.

how is the chroot command used to change directory of the user

you can change it in /etc/passwd file.

eg.
fake:x:1002:1002:,,,,:/home/fake:/bin/bash

fake:x:1002:1002:,,,,:<change_this>:/bin/bash

I have already done this but i am not quite satisfied. Actually i need two users to use same directory e.g. /home/default by many other users but the users cant find the /home/default directory because they are login are different. Is this logical?

>>>>Check that both users have rwx permissions to access the directory that you intend to use as home. then it should not be a problem!

I think it's smarter to group this two users and give permissions to folders that this two useres will use.
