1. Create a executable script. 🙂 Open your terminal first: Press the start button and type terminal and select the Console, Konsole, Terminal or anything but in the result of search. Use your desired editor to create a new file with .sh in the end of the file at any places. Just remember don't delete it. For vim, you type vi and path of your like. Example: vi /home/user/abc.sh For nano you type nano and path of your like. Example: nano /home/user/abc.sh 2. Getting the "modeline" thingy 😎 Before we get to the editing part, you need something named "modeline" which represents your configuration by into numbers code. Exit the editor.
