Our first shell script is the classic “Hello World”. This example demonstrates the basic structure of a shell script.

You can run this script by saving it to a file (e.g., hello-world.sh), making it executable with chmod +x hello-world.sh, and then running it with ./hello-world.sh.

The echo command prints text to standard output. It’s one of the most commonly used commands in shell scripting.

You can also print multiple lines using multiple echo commands, or use special characters.

The -n flag prevents echo from adding a newline at the end of the output.
