This script installs Tdarr on a bare metal ubuntu server.
It also creates the necessary services so tdarr starts automatically on boot.

#!/usr/bin/env bash

# Updated for Ubuntu 25.04 Bare Metal
# Secure: Runs Tdarr under unprivileged user and asks for group membership
# Ensure script is run as root
if [[ $EUID -ne 0 ]]; then
  echo " This script must be run as root. Please run it with:"
  echo "   sudo $0"
  exit 1

what sets that variable ?

Where would these functions come from ?

This honestly looks like some script that is supposed to run as part of some larger framework, not as a standalone shell script … without any further context nobody will be able to tell if it can or can not work …

3

I’m unfamiliar with scripting, but it’s sourced from:

That’s for proxmox.

4

So you should perhaps ask on https://forum.proxmox.com/ where you will likely find more expertise …

(It will cleartly not “just run” outside of the framework without some re-write)

5

Maybe, but the version I posted are for Ubuntu.
Link to my github:

6

Well, it will definitely not run as is since it relies on these functions and variables from the framework, I suggest just taking it as an example and write your own script from scratch using the essential bits from it as input …

It looks like /dev/stdin <<< “$FUNCTIONS_FILE_PATH” line was meant for modular Proxmox LXC templates.
