The term “shell” in Unix comes from a simple metaphor: it acts as a protective outer layer around the system’s core. - ChatGPT

# Run multiple commands and kill them as one

use subshells with background commands.

(command1 & command2 & command3)

# redirect sudo output

Run a shell with sudo and give the command to it by using the -c option

sudo sh -c 'ls -hal /root/ > /root/test.out'

Create a script with your commands and run that script with sudo

#!/bin/sh
ls -hal /root/ > /root/test.out
