Ok you can try this from home ; ) login in as a user ( non root ) set SHELL is set to SHELL=/bin/sh Ok now try su - (give password) set SHELL=/bin/csh Ok that makes sense Now /bin/sh set SHELL=/bin/csh WTF? Log out of all the login as root set SHELL=/bin/csh Ok that makes sense /bin/sh set SHELL=/bin/csh WTF? It looks to me ( if I am not missing something here ) That I can only get to sh by loging in as a user...Again WTF
