Make Bash Scripts in Linux


If you’re new to Linux, you may have heard of bash scripts but don’t know what they are or how to create them. Bash scripts are essentially a series of commands and instructions that can be executed in a Linux terminal. These scripts can save you time and effort by automating tasks that you would normally have to do manually. In this article, we’ll go over the basics of how to make bash scripts on Linux and provide some examples to get you started.

Getting Started

To get started with creating bash scripts, you’ll need to have a text editor installed on your Linux system. Popular text editors include Vim, Emacs, and Nano. You can use any of these editors, but for this article, we’ll use Nano. To install Nano, open a terminal and run the following command:

sudo apt-get install nano

Once you have Nano installed, you can start creating your first bash script.

Creating Your First Bash Script

Open a terminal and type the following command to create a new file called “”:


This will open up the Nano editor, where you can start typing your bash script. The first line of your script should be the shebang, which tells the system which interpreter to use. For bash scripts, the shebang should be:


After the shebang, you can start typing your commands. For example, if you want to create a script that prints out “Hello, World!”, you can type:


echo "Hello, World!"

Save the file by pressing “Ctrl+O” and then exit Nano by pressing “Ctrl+X”. Make the script executable by running the following command:

chmod +x

Now you can run the script by typing:


This will execute the commands in your script and print out “Hello, World!” in the terminal.

Using Variables in Bash Scripts

Variables are a powerful feature in bash scripts that allow you to store and manipulate data. To create a variable in a bash script, you can use the following syntax:


For example, if you want to create a variable called “name” and assign it the value “John”, you can type:


echo "Hello, $name!"

When you run this script, it will print out “Hello, John!” in the terminal.

Using Loops in Bash Scripts

Loops are another powerful feature in bash scripts that allow you to repeat a set of commands multiple times. There are two main types of loops in bash scripts: for loops and while loops.

For loops iterate over a list of values, while while loops repeat a set of commands as long as a certain condition is true.

Here’s an example of a for loop that prints out the numbers 1 through 5:


for i in {1..5}
  echo $i

This script will print out:


Here’s an example of a while loop that repeats a set of commands until a certain condition is met:



while [ $count -le 5 ]
  echo $count

This script will print out the same numbers as the for loop example above.


Bash scripts are a powerful tool for automating tasks in Linux. With the examples provided in this article, you should be able to get started with creating your own bash scripts. Remember to start with a she

bang, add your commands, save the file, make it executable, and run it in the terminal. Don’t be afraid to experiment with variables, loops, and other features to create more complex and useful scripts.

As you create more bash scripts, you may find it helpful to organize them into a dedicated directory. You can create a directory called “scripts” in your home directory by typing:

mkdir ~/scripts

Then you can save your scripts in this directory and access them easily from the terminal.

Finally, keep in mind that bash scripts are not just limited to the commands and features covered in this article. There are many more advanced features and techniques that you can use to create even more powerful scripts. The best way to learn is by doing, so keep practicing and exploring the possibilities of bash scripting in Linux.
