Restricted_shell
The restricted shell is a Unix shell that restricts some of the capabilities available to an interactive user session, or to a shell script, running within it. It is intended to provide an additional layer of security, but is insufficient to allow execution of entirely untrusted software. A restricted mode operation is found in the original Bourne shell[1] and its later counterpart Bash,[2] and in the KornShell.[3] In some cases a restricted shell is used in conjunction with a chroot jail, in a further attempt to limit access to the system as a whole.
