This article will show you how to use function (create / call function) in Bash.

Creating a function:

my_function () {
    <commands>
}

Another way:

function my_function {
    <commands>
}

Calling a function:

my_function () {
    <commands>
}

my_function

Practical example

#!/bin/bash

my_function () {
    echo "Hello from function"
}

my_function
my_function

Output:

Hello from function
Hello from function
