I am developing a command line application that uses Vim to edit an existing file. Think visudo or crontab -e.

Is there any command line option that I can pass to Vim to disable shell commands?

    Could you provide some more detail about what you're trying to do, to demonstrate the problem? What is being escaped, and why don't you want it escaped? – JigglyNaga Feb 7 '18 at 14:32
  • Just FYI, the term "shell escaping" is usually used in Vim to refer to the practice of altering string-format commands in order that they are interpreted correctly by the shell. See :help shellescape(). What I think you're talking about is usually referred to as "shell commands" or sometimes "shelling out". – Rich Feb 8 '18 at 11:06

The -Z (restricted mode) command line option is what I'm looking for. This provides sufficient protection against :! being used. Thanks to Rich and B Layer for pointing this out in my sister question, "Prevent saving buffer with new name"
