Run text file as commands in Bash

Question

If I have a text file with a separate command on each line how would I make the terminal run each line as a command? I just don't want to have to copy and paste 1 line at a time. It doesn't HAVE to be a text file... It can be any kind of file that will work.

example.txt:

sudo command 1 sudo command 2 sudo command 3

Answer 1

You can make a shell script with those commands, and then chmod +x <scriptname.sh>, and then just run it by

./scriptname.sh

Its very simple to write a bash script

Mockup sh file:

#

!/bin/sh sudo command1 sudo command2 . . . sudo commandn
