Help with a simple BASH script creation

Question

The problem

My 16gb LiveUSB session for Ubuntu 12.04 doesn't save certain settings/applications on the persistent section. I must shut down my laptop, thereby erasing everything stored on RAM (I am currently without a hard drive.)

---

The goal

To write a script that:

- Will set power management for wlan0 to OFF
- Will await keyboard input from user (as I must then join a wireless network)
- Will then accept an input from any key to proceed
- Will download and install Adobe Flash
- Will download and install Chromium Browser

*I will, then, transfer this script to the persistent section of my USB dongle.

The question

Is this even possible and if so, how would I even get started? I have no prior education in coding. However, I grasp the concept. All I'm looking for is a little direction so that I may get started with programming an actual solution to my real-world problem.

Thanks in advance!

Answer 1

You can put something like this on your Desktop as script.sh and run it with a double-click every time you want to install the software:

#!/bin/bash
sudo iwconfig wlan0 power off
echo "Press any key to continue with Adobe Flash/Chromium installation. "
read -n 1 -s
sudo apt-get -y install flashplugin-installer chromium-browser
exit

iwconfig wlan0 power off turns off power management. echo just prints a line of text. read -n 1 -s waits for keyboard input. apt-get installs the packages. exit closes the terminal session.
