Run text file as commands in Bash

Solution 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

Solution 2:

you can also just run it with a shell, for example:

bash example.txt

sh example.txt

Solution 3:

Execute

. example.txt

That does exactly what you ask for, without setting an executable flag on the file or running an extra bash instance.
