It will look like this:Īfter you do this the editor will exit and save your script. I will be saving the file as “directories.sh”. After that, the system will ask you for confirmation and then it will ask you to write a name for the file. When you are done with the commands that are mentioned above then you press CTRL + X to save the script and exit. So, the list of commands goes as follows: #!/bin/bash The script usually starts with #!/bin/bash so you first need to write this. The above command will open the Nano editor that will look something like this:

This is usually already installed in Ubuntu. Now, at the very beginning, you need to type “nano” in the terminal window to open the text editor. File extensions on Linux are optional, but it is a good practice to name shell scripts with the “.sh” extension. The editor is called ‘Nano’ and the shell scripts have a “.sh” extension. This works on any recent Ubuntu version incl. We will use one of the built-in editors in Ubuntu to write a simple script. The shell is an interpreter of the commands that the user writes. Then, when the user needs to do a particular task, all he has to do is run the saved script and the task is done without having to write all the commands again one by one. To complete this task, you simply write all the commands in a single script and save that script file somewhere. Think of it like this: You have a task to do, for which you need to write a certain number of commands, and it is difficult to write and execute these commands one by one. When a user executes the script, all the commands that are in the script are executed one after another. A shell script is a Linux-based script in which commands are written.
