Yeah, but make sure to check with `ls -l` after!

So all users can read it by default? That's interesting!

Wait, why would Harry need zero permissions? Seems harsh!

Don't forget to set the ACLs for Natasha and Harry.

Just use `cp -a` to copy the file!

I practiced a similar question, and I think the order of commands matters. We should copy the file first before changing permissions, right?

I recall that the default permissions might allow read access for others, so we might not need to set that explicitly.

I think we need to use `chmod` to set the permissions, but I’m a bit confused about how to ensure harry has no access.

I remember we practiced setting file permissions, but I’m not sure if I got the ACL commands right for natasha and harry.

I’m pretty sure the command to copy the file is `cp`, but I can't recall if we need to use any options with it. Should we use `-a` or just a simple `cp`?

I practiced a similar question where we had to set permissions for multiple users. I think the default permissions will allow others to read, but we need to check with `ls -l` after setting everything up.

I remember something about using `setfacl` for specific user permissions, but I’m a bit confused about how to deny Harry access while allowing Natasha to read and write.

I think we need to use `chown` to set the owner and group for the file, right? I'm not entirely sure about the exact syntax though.

I'm a little confused by the options presented. None of them seem quite right to me. I'll have to review the Flutter documentation on floating action buttons to make sure I understand the correct approach.

This seems like a pretty straightforward question. I'd go with change management - that's usually the first step when making any kind of configuration changes.

Ugh, log searching is the worst. I'm just going to guess and hope for the best. Maybe option C will work?
