Yup, --d checks directories, --f checks files. Simple!

--z is for strings, not files!

Wait, are you sure about --f? I thought it was for files only.

--d and --f are the ones for file system checks.

I feel like --eq and --lt are more about numerical comparisons, so they probably don't apply here.

I practiced a similar question last week, and I think --d is definitely for directories, but I can't recall if --f is the other one.

I'm not entirely sure about --z, but I remember it being related to string tests, not file system elements.

I think --d and --f are the ones that check for directories and files, right?

Let me see... I'm pretty sure --z and --d are not file system operators, but I'm not 100% sure about the others. I'll have to think this through.

I've got this! The two correct answers are --eq and --f. I'm confident in my knowledge of file system operations.

Wait, what are the file system comparison operators again? I'm a bit fuzzy on those.

Hmm, this is a tricky one. I'll need to think carefully about the file system comparison operators.

Okay, I know the file system operators pretty well, so I think I can handle this. Let me review the options.

I'm a bit unsure about this one. I want to double-check the steps to make sure I'm not missing anything important.

Okay, let me think this through. The engineer installed a device to automatically detect the missing caddy and prevent the door from closing. That sounds like a Poka yoke solution, which is designed to prevent defects by making it physically impossible to make the mistake. I'm feeling good about that being the right answer.

I don't think --z is used for file system elements. It's more for checking if a string is null.
VA

I'm not so sure about that. I think --z could also be one of the comparison operators.
LE

I agree with you, --d checks if the file exists and is a directory, while --f checks if the file exists and is a regular file.

I think the operators that work on elements in the file system are --d and --f.
