How to run bash script as root from user user?

Question

I have a couple of commands that need to be run from root

cd FolderName
sudo su
export VARIABLE_NAME=120
. install/setup.bash
ros2 run node node

I tried to create a script from these commands, but after the sudo su command, the script stops.
How can I run this set of commands under the root bash script?

Re: "after the `sudo su` command, the script stops": I doubt this. Rather, what's happening is that the `sudo su` command is running, waiting for you to type commands for it to run as root. If you were to type `exit`, the `sudo su` command would complete, and then the rest of the script would run (but as you, not as `root`). — ruakh, Aug 26 '19 at 06:25

The best way to do this, run the script as root user like,

$ cat install.bash
#!/bin/bash

cd FolderName
export VARIABLE_NAME=120
. install/setup.bash
ros2 run node node

And then run as root,

$ su root install.bash

And can you somehow automatically specify a password in the script so that the user would not have to write it manually? – DR.zarigan Aug 26 '19 at 09:54
I think, you could use `expect` utility – han solo Aug 28 '19 at 12:23
