Command Line Rocks

I simply love using command in Linux.   I currently using Linux Mint because I didn’t want to upgrade my laptop to Windows 10.   If you know anything about Linux, they seldom install the necessary apps for Laptops or Desktops.   You’d have to install them separately and some of the apps do some really useful things on Linux.   Such as the touch pad inidcator which will disable the touch pad when you are typing or when you are using a mouse.   I hate to use the Graphical User Interface to find and install these apps.  So I decided to create a shell script to install the needed laptop apps for any installation of Linux on a Laptop.  I do like to install programs from the GUI but that is when I am looking to install one program or just curious what they’ve added to the Synaptic Package Manager.   Since most of these apps are open sourced, I thought it would be nice to show you how to create a shell script that you might want to use from time to time.  The nice thing this helps if you are re-installing Linux or installing Linux on a new laptop Linux.

Creating a Shell Script

Before you begin this process, you’ll want to wrap your head around how to create the Linux script.  Once you learn about the process of creating the script.  You will understand more about the next process but you should at least get the basics so you can know what you can and can’t do in a script.   A shell script is almost like a batch file in Windows and you can do a lot of things in it.  Some things you can do are If/then or Echo, or Sudo commands.   If you want to make a complicated menu then that is fine also. I believe simplistic is best.   So I created my own little simple script to install the laptop apps that will help me on my laptop.

Laptop-linuxinstall.sh

echo Installing Touchpad Inidcator
sudo add-apt-repository ppa:atareao/atareao
sudo apt update
sudo apt install touchpad-indicator

echo installing cpu frequency Inidcator
sudo add-apt-repository ppa:artfwo/ppa
sudo apt update
sudo apt-get indicator-cpufreq

echo Installing Battery Optimization
sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw
sudo tlp start

echo Installing Laptop Mode Tools
sudo add-apt-repository ppa:ubuntuhandbook1/apps
sudo apt-get update
sudo apt-get install laptop-mode-tools

You could easily copy this and paste it into a text editor and start using it right away but I hope you at least learn about scripting.   This script will work with Linux Mint or Ubuntu, but I am unclear if it will work with other Linux OS.  This is why you will want to learn the create your own script because you might have to modify or add new lines into the script.  If you decide to use Laptop Mode tools, I suggest you read about how to configure the tools once you installed it.

Changing Permissions

Once you have created the script and saved it to a file you will need to change the permissions of the file so Linux can run it from command line or if you decide to run it from the GUI.   You can either right click the file > Properties then go into permissions (See above for example) and check mark “Allow executing file as a program” or go into terminal mode.

Go to where the file is located and type “sudo chmod +x filename.sh”  and enter your Password.  Once this is done you can now either use the GUI or type “./locationoffile/file.sh” in the terminal.

All is Good!

After you have done all that, You now should keep the shell script on several locations so you can always use it if you need it.   I occasionally like to reinstall Linux to keep the system running smoothly so that is why I created shell scripts to install my favorite programs or stuff I might want to use on my laptop.   Do you have a favorite application or a suggestion please feel free to leave a comment below.   I’d love to hear what you install on your Linux OS and why.
