Thanks Frank

I attach my script for you.

SO, how to run script after login automaticly. ie: when the user login the menu in the scipt will the only one he can use it. and if the user chose EXIT, then he logout from the system.

I found in some forums smothing like :
- How to create a restricted shell user in 4.2 and 5L . and he will be able to execute some come commands.

- There is a lot of different ways to do this but I found the best way is to
1. Create a user on the system that will be used for this
2. vi /etc/password file and change the user to match root users eg ....
new_user_name:*:202:1::/etc/ipsec:/usr/bin/ksh
from this to this
new_user_name:*:0:0::/etc/ipsec:/home/new_user_name/menu_script_file_name.ksh
3. As you can see this user will have the same access as root but will not have a shell.

4. You now need to create a shell script that has a menu function that will allow for selection of the command you need to run. ( do net give shell access only scripts )
5. The user can not break out of the menu as he has no shell and will be logged out. 6. set the password for the user

I try it and not work for my script .

PLZ. help need it.

chsh

CHSH(1) 							   User Commands							   CHSH(1)

NAME

       chsh - change login shell

SYNOPSIS

       chsh [options] [LOGIN]

DESCRIPTION

       The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
       the login shell for her own account; the superuser may change the login shell for any account.

OPTIONS

       The options which apply to the chsh command are:

       -h, --help
	   Display help message and exit.

       -R, --root CHROOT_DIR
	   Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.

       -s, --shell SHELL
	   The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.

       If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
       value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.

NOTE

       The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
       and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
       in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
       back to its original value.

FILES

       /etc/passwd
	   User account information.

       /etc/shells
	   List of valid login shells.

       /etc/login.defs
	   Shadow password suite configuration.
