RuneAudio Forum

I tried to install a hardware switch (ON/OFF ShHIM from Pimoroni). It needs to run an install script:

curl https://get.pimoroni.com/onoffshim | bash

When I trie that, it does not install the script but tells me something else:

"Running as root, please log in as a regular user with sudo rights!"

I do not understand, does that mean that a nromal user using "su" can do more than root? What is it that I need to do to install the script?

Thanks in advance for the help, kindest regards, Stefan

Hi klettervirus,
Linux has got very particular about what can and what can not be run as root. You also have a script designed for one of the standard Linux versions like Rasbian. RuneAudio uses Arch-Linux which uses a formal publication and version control process. So there is no guarantee that your script will deliver what is should.
As you point out it seems a waste of time forbidding things to be run as root then insisting that they are run as root via sudo. But I am afraid that’s the way it is.
I suggest you make a user called ‘shim’ and try using it to run the script. Create the user:

Code: Select all

userdel shim
groupdel shim
groupadd -r shim
useradd -r -d /home/shim -g shim shim
mkdir /home/shim

then add a file to the directory /etc/sudoers.d, for example: sudo-shim:

Code: Select all

nano /etc/sudoers.d/sudo-shim

With this content:

Code: Select all

shim ALL=NOPASSWD: ALL

Copy the script to directory /home and run:

Code: Select all

chmod 777 /home/<scriptname>

Then we should be ready to go, switch to the user shim with this:

Code: Select all

su shim

To check who you are:

Code: Select all

whoami

Then run your script:

Code: Select all

cd /home
sudo <scriptname>

That should do it. You can exit the shim user environment with:

Code: Select all

exit

Check who you are with whoami.

PS do not forget to clean up afterwards:

Code: Select all

rm /etc/sudoers.d/sudo-shim
userdel shim
groupdel shim
rmdir /home/shim

Thanks so much, will try that!

This way can realize the shutdown state, click the button to start it?

I do not know if stablgr succeeded in making it work. Collin uses an elegant power switch configuration. However this looks like a better solution than using python scripts: https://github.com/ali1234/systemd-gpio
