Shell Script#

Here is a Bash script with a function:

#!/bin/bash

function greet {
    echo "Hello, $1"
}

greet "World"

Explanation#

• function greet { ... }: This line defines a function named greet.
• echo "Hello, $1": This command prints a greeting message using the first argument passed to the function.
• greet "World": This line calls the greet function with the argument “World”.

Conclusion#

By using functions in your Bash scripts, you can encapsulate and reuse code, making your scripts more modular and maintainable.
