    Shell scripting is a powerful tool for automating tasks in Linux. It allows you to write a sequence of commands in a file and execute them, saving time and effort. Shell scripts can be used for various purposes such as task automation, file management, and customization of the command line environment.

    Creating and Running a Shell Script

    To create a shell script, you need to follow these steps:

    • Create a script file: Use a text editor to create a file with a .sh extension. For example, hello_world.sh.

    • Add the shebang: The first line of the script should be the shebang (#!) followed by the path to the bash interpreter. For example:

    #! /bin/bash
    Copied!

    • Write commands: Add the commands you want to execute. For example:

    echo "Hello World"
    Copied!

    • Make the script executable: Use the chmod command to give execution rights to the script. For example:

    chmod +x hello_world.sh
    Copied!

    • Run the script: Execute the script using the following command:

    ./hello_world.sh
    Copied!
