* this was my first reaction as well; in many years of BD and Drupal dev I've never had occasion for this; so i'm curios as to what your use case is.
> Can I do this securely?
depends on a lot
what is the bash script doing? is just `ls` then prolly fine
who can access it; admin only; everyone?
> Can anyone point me at any existing sample code?
@bwpanda has shown how `drush` is doing it; should work in backdrop too, but it should be pointed out a `drush` user is a cli user and already has access to cli and bash scripting ... that is a big difference
> How would I do this?
the how is in the `drush` example.
Might be better to tell us about your use case and find an alternate method to what you are trying to accomplish.
But I agree with everyone else, however that gets called needs to be completely locked down. My off the cuff suggestion is to not have this in a module, but have it embedded into a page and use the normal roles/permissions to lock the page down. Basically KISS.
However, it's not clear to me that this is a good option and I understand the concerns.
We are currently experimenting with another option. We have set up a script that runs on periodic basis. Each time the script runs, it checks the database for a new request. If there is a new request for a specific action, it runs another script on the server to fulfill that request.
In this case, the script is only looking for specific values and if that specific value is present, it takes the action requested.
This seems like it's a lot safer. Any thoughts?
Happy to discuss the specifics with anyone in Zulip. :-)
Have you tried uc_cart_add_item()? You need to provide the nid of the product. Then you can use backdrop_goto('cart/checkout'); to send the user to the checkout screen. uc_cart_add_item...

No problem, let's see how it evolves.
I'd be happy to provide a suggested version if i could.
I will keep that in mind and try learn this hook chain hopefully very soon. I will...

I could request hashing support, but that's the lazy way
🤣
I would appreciate it if you as an active maintainer would 'officially' add a hashing support...
Hi, i understand the updating obstacle - not worth mentioning - hence it is a wacky (but working) patch until i know what to do. :-)
One of my biggest wishes is to understand the hook...

Here's an example of Drush calling the `fix-permissions.sh` script: https://github.com/backdrop-contrib/drush/blob/2b439610d644a0d82f541b047...
You could use that as a basis for your hypothetical code.
My first reaction when I read this was "You shouldn't" 😅...
...but if you are to, then I would suggest to also pair it with a
user_access()and/oruser_has_role()check.If you want to run the script while not logged in, then I'd also add a token to the mix (see how the cron URL token works).

Ignoring "If you should..."
A Backdrop module is just PHP, so, first result from Google:

I did some experimenting and was able to run a bash script located within the Drupal directory using the php function:
https://www.php.net/manual/en/function.exec.php
However, it's not clear to me that this is a good option and I understand the concerns.
