What Is Basic Scripting Linux?


Angela Bailey

Basic scripting in Linux refers to the practice of writing small programs or scripts to automate tasks and perform various operations on a Linux system. These scripts are written using scripting languages like Bash, Perl, Python, or Ruby. In this article, we will explore the basics of scripting in Linux and how it can be used to simplify and streamline your daily tasks.

Why Scripting in Linux?

Scripting in Linux is a powerful tool that allows users to automate repetitive tasks, increase productivity, and customize their system according to their needs. With scripting, you can save time by creating a script that performs complex operations with just a single command.

Getting Started with Basic Scripting

Before we dive into writing scripts, it’s important to understand some basic concepts. Scripts are simple text files containing a series of commands that are interpreted by the shell or interpreter specified at the beginning of the script.

Choosing a Scripting Language

Linux offers various scripting languages, each with its own strengths and weaknesses. Let’s take a look at some popular options:

  • Bash: The Bourne Again Shell (Bash) is the default shell for most Linux distributions. It provides excellent compatibility with existing Unix commands and is well-suited for system administration tasks.
  • Perl: Perl is a powerful language known for its rich text processing capabilities.

    It’s often used for tasks like file manipulation, text parsing, and network programming.

  • Python: Python is a versatile language known for its simplicity and readability. It has an extensive standard library that makes it suitable for various purposes such as web development, data analysis, and automation.
  • Ruby: Ruby is an object-oriented scripting language with an elegant syntax. It’s popular for web development and offers a wide range of frameworks and libraries.

Writing Your First Script

To start writing a script, open a text editor and create a new file with the desired scripting language extension (e.g., .sh for Bash, .pl for Perl, .py for Python). Let’s create a simple Bash script to display a “Hello World” message:

echo “Hello World!”

In this example, the first line specifies the interpreter (Bash in this case) to execute the script. The second line uses the `echo` command to print the message “Hello World!” to the terminal.

Running Scripts

To run a script, you need to make it executable. In Linux, you can do this using the `chmod` command:

chmod +x hello.sh

After making the script executable, you can run it by typing its name preceded by `./`:


The output will be displayed on your terminal.

Scripting Examples

Now that you have an understanding of basic scripting in Linux, let’s explore some examples of how scripts can be used in practical situations:

  • Automating Backups: You can write a script to automatically backup important files or directories at specified intervals.
  • System Monitoring: Scripts can be used to monitor system resources like CPU usage, disk space, and memory usage.
  • Software Installation: Instead of manually installing software packages one by one, scripts can automate the process by installing multiple packages with just one command.

In Conclusion

Basic scripting in Linux is a valuable skill that can greatly enhance your productivity and simplify your daily tasks. By automating repetitive tasks and customizing your system, you can save time and effort. Whether you choose Bash, Perl, Python, or Ruby, scripting opens up a world of possibilities for Linux users.
