How to write a script and have it run on Ubuntu 16.04 boot

Question

I have figured out how to use Terminal to change my Apple Magic Mouse settings to be how I like them. I am using the following lines of code.

remove mouse module settings

$ sudo rmmod hid_magicmouse

add faster scrolling settings

e$ sudo modprobe hid_magicmouse emulate_3button=0 scroll_acceleration=1 scroll_speed=55

reverse scroll direction

xinput set-button-map 14 1 2 3 5 4

When I restart the computer, all these setting are lost and I have to re-input them into terminal.

How do I create a script, and where do I save it so that it will run every time I boot the computer.

I am a complete novice in Ubuntu so I don't even know what file extension to use. Thanks in advance for your help.

Answer 1

To create a script so that it will run the commands by a single execution of that script, you need to create a file with '.sh' extension.

Open the terminal, and in a suitable directory, create a script file.

    $vi <name you prefer>.sh

This is will open the VI editor. Or you can choose any other editor if you prefer. Then add each command in a new line, and then save the file. Your file should look something like

    #!/bin/sh
    sudo rmmod hid_magicmouse
    sudo modprobe hid_magicmouse emulate_3button=0 scroll_acceleration=1 scroll_speed=55
    xinput set-button-map 14 1 2 3 5 4

Now set the executable permissions to this file,

    $chmod +x <nameoffile>.sh

And now execute the file,

    $sudo ./<nameoffile>.sh

Execute the file with sudo permissions as your commands need to executed as superuser. Your mouse settings should have taken their place.
