I’m a bit confused. I thought it was `!`, but now I’m second-guessing myself. Maybe I need to review that section again.

I feel like I saw a similar question in our practice tests, and I think it was definitely `&` that runs commands in the background.

Ah, the old background process trick. It's definitely the ampersand (&) character that you add to the end of a command to run it in the background. That's a classic shell technique that I'm familiar with.

I'm a little confused by this question. I know there are different ways to run commands in the background, but I'm not sure which specific character is used. I'll have to review my notes and try to remember the right syntax.

Hmm, I'm a bit unsure about this one. I know there are a few different ways to run commands in the background, but I can't remember the exact character off the top of my head. I'll have to think this through carefully.

I'm pretty sure it's the ampersand (&) character, since that's the standard way to run a command in the background in many shell environments.

The ampersand (&) is the answer, no doubt about it. That's the classic way to background a process in the shell. I've used that trick many times before.

I'm a little confused on this one. Linkedin is for professional networking, so that doesn't seem quite right. Pinterest is more for visual inspiration, so that's probably not the best fit either. I'll have to re-read the question.

I'm not sure about this one. The wording of the question is a bit confusing, and I'm not entirely confident in my understanding of how foreign key constraints work in this scenario.
