Hm, I'm not sure this is a safe assumption to make. That is, it's possible to have a different arg passed to Terraform that is a file—or worse yet, happens to match the name of a valid file—but isn't a plan file. Here's an example:

terraform apply \ 
  -state foo.tfstate \
  -var foo=bar

If there's a foo.tfstate already, the code above will move that parameter to the end of the command, as if it's a plan file.

Thank you @brikis98, I haven't considered that use case. I will write a test as well as validating the current ones work fine and come back to you.

for _, arg := range argsToInsert {
if util.IsFile(arg) {
lastArg = arg
} else {
args = append(args, arg)
}
}

args = append(args, terragruntOptions.TerraformCliArgs[commandLength:]...)

// Append lastArg which is a Terraform plan file
if lastArg != "" {
args = append(args, lastArg)
}

terragruntOptions.TerraformCliArgs = args
}
