Writing a new Shell is not trivial. What programming level have you reached?
If this is a course task you may find reading about the "chroot" command useful (but don't issue the command unless you know what you are doing).
Most main Shells come with a Restricted version. e.g. "rksh" is the restricted version of "ksh".
SIR,
i have created a new shell.....now i m luking at various commands that can be restricted for the students during exams so that they dont use previously written programs,,,,....advice on better book names for this purpose would be of great help...thanks alot for ur reply....i almost have lost all hope of completing the project on time...
