Wait, isn't 775 too permissive?

I feel like option A is close, but I can't recall if the syntax is exactly right for setting those specific permissions.

I practiced a similar question where we had to set permissions for a script, and I think 775 might allow too much access.

I remember something about using numeric codes for permissions, but I'm not sure if 577 is correct for this scenario.

I think the command needs to give execute permissions to everyone, but only the owner should have write access.

I'm going to go with option A. The permissions u=rwx,go=rx seem to match what the question is asking for.

I'm a bit confused by the wording of the question. Can someone explain the difference between "executable by everyone" and "writable only by its owner"?

I've got this! The answer is definitely C - chmod 577 /bin/foo. That sets the permissions exactly as described.

Option C seems like the right choice to me. The 577 permissions give everyone execute access, but only the owner can write to the file.

I think option A is the correct answer, as it sets the permissions to rwx for the owner, and rx for the group and others.

I'm not sure, but I think C) chmod 577 /bin/foo might also work because it sets specific permissions for the owner, group, and others.
