Wow - yet another command I'd not heard of, which I had to research!

I'll therefore go for [HIDE]B[/HIDE]

Harry.

 

[HIDE]Never heard of it either but I have a hunch <google> it's...

B
[/HIDE]

 

I'll guess [HIDE]B[/HIDE]

 

You all got it. The right answer is "B". The -a option sets the file attribute so that it can only be appended. The plus sign ( + ) adds the attribute. A minus sign ( - ) would remove it.
