Hello everyone,
I hope i'm in the good place to start with.
Here is my question : I've been looking for a way to set a defined behaviour when zsh is reading from the command-line, i've come across Zshzle but can't find anything related to what I would like to do :
I would like to start all of my commands with a special character and if it's not there, call my "lock" alias.
Let's say I have the following command line :
"vim ~/.bashrc"
then it would call my "lock" alias and lock my computer, as the "good" input would have been "h vim ~/.bashrc".
Any suggestions ?
Thanks

You can do that with Hooks, but to be honest, this seems like not a good solution against anything but the most naive meddling.

Which is fine, though, maybe you want to prevent a child or a pet to trigger a command, so, yeah.

There is also 'accept-line' that you could override, but that can mess things up quite a bit since it tampers with one of the more fundamental bits of zsh.

Anyway, don't use this as a serious security measure. Checking aliases and the shell rc files are easy and obvious targets for inspection and there are most likely tricks to get around the hooks, too.
(I honestly don't know them, or I'd tell you them.)
