shell escape in "vi"

[Arun Kumar Krishna]

Hi,

I would like to know if it is possible to disable the
shell escape option in vi. I am trying to fork vi from
my program and I dont want anybody to use "!" or ":sh"
and execute shell commands. Any ideas??
or are there any other unix editors which wouldn't allow
this?

TIA
Arun

Well, for "standard vi" there seems to be no way.
However, some of the vi clones allow a shell restriction.
(Don't know which clone offers what exactly.)
Too bad that you will thus lose filtering. :-(

Anyway, a "shell restricted compile option" is on the wishlist for Vim.

I think there were some. I am sure some people here will tell you.

I'm not sure but I think nvi has a 'secure' option (-R ou -S) that does
exactly what you want;

Yeah,

-S Run with the secure edit option set, disallowing
all access to external programs.
