You mean, change his working directory, I suppose?

There are "restricted" versions of many shells, like rksh or rbash. They pose a set of restrictions on a user.

See Man Page for bash (linux Section 1) - The UNIX and Linux Forums for example and read the section "RESTRICTED SHELL".

Maybe rbash is not present on your system yet (it isn't here either).

Just create a hard link

Code:
cd /bin
ln bash rbash

If your bash is in a different location, then create the link there.

If i just create a hard link, will it work as a restricted shell.

Is that hard link creation enough.

will it restrict particular user not to change their home directories?

Sorry to ask you so many doubts.

Thank u very much for your responses.

You may also have to add /bin/rbash (or whatever) into /etc/shells so that all the administrative commands will work and SSH login is accepted.

It should work, because the shell checks the name under which it was started and if the filename starts with "r", it behaves as restricted.
