What Is Bash Scripting Called?


Larry Thompson

Bash scripting, also known as shell scripting, is a method of writing and executing scripts using the Bash shell. Bash is a Unix/Linux command language interpreter that provides a command-line interface for users to interact with their operating systems. It is the default shell on most Linux distributions and macOS.

Why Is It Called Bash Scripting?

The name “Bash” stands for “Bourne Again SHell.” It was created as a replacement for the original Bourne shell (sh) and incorporated features from other shells such as the C shell (csh) and the Korn shell (ksh). By combining elements from different shells, Bash became a powerful and versatile tool for automating tasks and writing scripts.

What Is a Script?

A script is a file containing a sequence of commands that are executed by the computer’s operating system. Scripts allow users to automate repetitive tasks, perform complex operations, or even create entire applications. In the context of Bash scripting, these scripts are written using commands specific to the Bash shell.

How Does Bash Scripting Work?

Bash scripting works by writing a series of commands in a text file with a .sh extension. This file is then passed to the Bash interpreter, which reads and executes each command in order.

Here’s an example of a simple Bash script:

# This is a comment
echo "Hello, World!"

In this script:

  • The first line #!/bin/bash specifies the path to the Bash interpreter.
  • The second line starts with #, indicating that it’s a comment. Comments are ignored by the interpreter and are used to provide explanations or documentation.
  • The third line uses the echo command to print the string “Hello, World!” to the terminal.

Executing a Bash Script

To execute a Bash script, you need to make it executable using the chmod command. For example:

chmod +x script.sh

Once the script is executable, you can run it by typing its filename preceded by ./, like this:


Common Uses of Bash Scripting

Bash scripting is widely used for various purposes, including:

  • Task automation: Scripts can be used to automate repetitive tasks, such as file backups, system maintenance, or software installations.
  • Data processing: Bash scripts are often used for processing and manipulating data files, such as CSV or log files.
  • System administration: Administrators use Bash scripts to manage and configure systems, set up user accounts, or monitor system resources.
  • Application deployment: Bash scripts can be used to deploy and configure applications on servers or cloud platforms.


Bash scripting is a powerful tool for automating tasks and writing scripts in Unix/Linux environments. It provides users with a flexible command-line interface for interacting with their operating systems. By mastering Bash scripting, you can simplify complex tasks and increase your productivity as a developer or system administrator.
