How to intercept/evaluate a shell command, run logic on the command and potentially kill the command

QUESTION

How to intercept/evaluate a shell command, run logic on the command and potentially kill the command

Asked 2020-Nov-16 at 10:46

There is a command line tool at my company that many people will use, but we need to set some restrictions on the tool's usage based on the environment that the user is in.

For example, if the user is logged into our production environment and they run dbt run , I need to flash a warning and prompt them to continue or exit.

I use zsh myself and found the preexec() hook, but unfortunately, because of the way this is implemented, calling exit kills the whole shell and closes the terminal. This seems to be a non-starter for this option.

I'm looking for a pure bash alternative (many of my coworkers may not use zsh) that will allow me to evaluate a command before it's executed, run the command through some logic, and allow me to either kill the command or run it.

Here is the zsh function i wrote for reference:

What you need to do is create a wrapper around the original command, not mess with preexec and other shell-specific hooks. Of course, you can write this wrapper itself as a zsh script. So you'll create, e.g., dbt_safe.zsh which would internally call dbt, and your colleagues would just use dbt_safe.zsh.
