I disagree, plan is more about what will change, not just errors.

I thought it was A, terraform plan? It shows changes too.

No way, it's D for sure. Validate checks for errors in .tf files.

I’m surprised terraform check isn’t a thing. Sounds useful!

I feel like `terraform check` isn't a real command, so it must be one of the others. I lean towards `terraform validate` too.

`terraform fmt` is more about formatting the files, right? I don't think it helps with error checking.

I remember practicing with `terraform plan` for checking changes, but I don't think it specifically validates the .tf files.

I think the command we need is `terraform validate`, but I'm not entirely sure if it checks the existing state as well.

I'm a bit confused on this one. I know there are a few different Terraform commands that can check the infrastructure, but I'm not sure which one specifically checks both the .tf files and the existing state. I'll have to think this through a bit more.

Definitely go with terraform validate. That's the command that checks the .tf files for errors and validates the configuration before applying any changes.

I'm not sure about this one. I know terraform validate checks the syntax of the .tf files, but I'm not sure if it also checks the existing state. Maybe terraform check is the right answer?

I think the answer is terraform plan. That command checks the .tf files for errors and also shows the changes that will be made to the infrastructure.
