And even more sed fun - inserting a file into a file ...

Following on from an earlier post: -

More fun with sed

I can also choose to insert a whole block of text: -

cat insert.txt

  backend "s3" {
    bucket                      = "$bucket"
    endpoint                    = "$endpoint"
    force_path_style            = true
    skip_region_validation      = true
    skip_credentials_validation = true
    skip_metadata_api_check     = true
    key                         = "$object"
    region                      = "$REGION"
  }

into an existing Terraform file: -

cat version.tf

terraform {
  required_providers {
    aws = {
      version = ">= 2.7.0"
      source = "hashicorp/aws"
    }
  }
}

as follows: -

sed -i '/terraform {/ r insert.txt' version.tf

which gives us the following: -

cat version.tf
 
terraform {
  backend "s3" {
    bucket                      = "$bucket"
    endpoint                    = "$endpoint"
    force_path_style            = true
    skip_region_validation      = true
    skip_credentials_validation = true
    skip_metadata_api_check     = true
    key                         = "$object"
    region                      = "$REGION"
  }

  required_providers {
    aws = {
      version = ">= 2.7.0"
      source = "hashicorp/aws"
    }
  }
}

Nice!
