The make command

The make command is used to automate the reuse of multiple commands in certain directory structure.

An example for that would be the use of terraform init, terraform plan, and terraform validate while having to change different subscriptions in Azure. This is usually done in the following steps:

az account set --subscription "Subscription - Name"
terraform init

How the make command can help us is it can automate all of that in just one go: make tf-init

Syntax:

make [ -f makefile ] [ options ] ... [ targets ] ...

Example use (guide):

1. Create Makefile in your guide directory

2. Include the following in your Makefile :

hello-world:
        echo "Hello, World!"

hello-bobby:
        echo "Hello, Bobby!"

touch-letter:
        echo "This is a text that is being inputted into our letter!" > letter.txt

clean-letter:
        rm letter.txt

3. Execute make hello-world - this echoes "Hello, World" in our terminal.

4. Execute make hello-bobby - this echoes "Hello, Bobby!" in our terminal.

5. Execute make touch-letter - This creates a text file named letter.txt and populates a line in it.

6. Execute make clean-letter
