A Peep into the World of Bash Scripting Before we get our hands dirty, let's clear the air on what Bash scripting is, and why it's such a big deal. Bash (Born Again SHell) is the default shell in most Linux distributions. It's your command-line interpreter, your digital genie, ready to obey your commands. What's a shell, you ask? Think of it as a user interface that lets you chat with your operating system, except the chatting involves more commands and less small talk. What about scripting? It's writing a series of commands for the shell to execute. Therefore, Bash scripting involves writing a list of commands for the shell to execute, automating repetitive tasks, and making your life easier. Sweet, isn't it? Bash Scripting 101: A Hands-On Journey Creating Your First Bash Script It's time to get the ball rolling! Your first Bash script isn't going to be rocket science; let's keep things simple. To create a Bash script, we will: Open a text editor. Write our commands. Save the file with a .sh extension. Let's echo "Hello World" - the classic programmer's greeting. #!/bin/bash
echo "Hello, World!" The #!/bin/bash is called a shebang. It tells the system that this is a Bash script. Running Your Bash Script Running a Bash script is as easy as pie. You just need to remember two steps: Give execute permissions to your script using the chmod command: chmod +x script.sh Execute the script: ./script.sh Voila! Your terminal should display "Hello, World!". You've just run your first Bash script. Variables in Bash Hold onto your hats because we're diving into the nitty-gritty of Bash scripting - variables! In Bash, we define a variable like this: VARIABLE_NAME="Hello, World!" And to use a variable, we use the dollar sign: echo $VARIABLE_NAME Conditional Statements in Bash Life is full of choices, and so is Bash scripting! Conditional statements help us choose between options. Here's a simple if-else statement: if [ $1 -gt 100 ]
then
  echo "That's a big number!"
else
  echo "Meh, that's a small number!"
fi This script checks if the argument you pass is greater than 100 and displays a message accordingly. Want more like this?
