block shell from each other

[Chris Campbell 77]

We have a user who's default shell is jshell and we want this user to only access this particular shell.

Is it possible to prevent the user switching from jshell to kshell?
Thanks

Do you have the source to jshell to change it to not invoke any but known commands?

Otherwise, what will prevent the user from copying ksh to foo_bar and then executing that?

Yes, shells pointed "while creating of the user account"

if you have already setup "jshell" for "particular user" with power of root privileges.

user will not able to "change shell" as long as " you change jshell to kshell -> using "root " privileges"
