Multiple Terraform File in the Same Directory

let's create the below files in the same directory add the below content in the first.tf file

output "firstoutputblock" {
        value = " this is first hello world block"
}

add the below content in second.tf file

output "secondoutputblock" {
        value = "this is second hello world block"
}

add the below content in third.tf file

output "thirdoutputblock" {
        value = "this is third hello world block"
}

now we have four files in our current working directory lets list them using ls command.

┌──(gaurav㉿learning-ocean)-[~/youtube-course/hello-world-file-destructure]
└─$ ls
first.tf  second.tf  third.tf

┌──(gaurav㉿learning-ocean)-[~/youtube-course/hello-world-file-destructure]
└─$

now let's run terraform plan command in the same directory.

┌──(gaurav㉿learning-ocean)-[~/youtube-course/hello-world-file-destructure]
└─$ terraform plan

Changes to Outputs:
  + firstoutputblock  = " this is first hello world block"
  + secondoutputblock = "this is second hello world block"
  + thirdoutputblock  = "this is third hello world block"

You can apply this plan to save these new output values to the Terraform state, without changing any real infrastructure.

──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if you run "terraform apply" now.

so, when we run terraform plan or apply command then all the tf files that are present in the present working directory are loaded.

Now I have a questions for you guys,

How these files will get loaded while running terraform plan?

so let's create one more file in abc.tf in the same directory with the below command

output "abc" {
        value = "this is abc hello world block"
}

now we have four files in our current working directory lets list them using ls command.

┌──(gaurav㉿learning-ocean)-[~/youtube-course/hello-world-file-destructure]
└─$ ls
abc.tf  first.tf  second.tf  third.tf

┌──(gaurav㉿learning-ocean)-[~/youtube-course/hello-world-file-destructure]
└─$

let's run terraform plan command and check the output.

┌──(gaurav㉿learning-ocean)-[~/youtube-course/hello-world-file-destructure]
└─$ terraform plan

Changes to Outputs:
  + abc               = "this is abc hello world block"
  + firstoutputblock  = " this is first hello world block"
  + secondoutputblock = "this is second hello world block"
  + thirdoutputblock  = "this is third hello world block"

You can apply this plan to save these new output values to the Terraform state, without changing any real infrastructure.

so the answer is all the files loaded in the alphabetic order.
