[aklug] file protection trick

As I keep a lot of stuff in ~, I'm susceptible to dangerous typos.
For example, a twitch of the thumb could turn:

$ rm junk*

into:

$ rm junk *

Something along these lines happened several years ago, and more
recently, I caught myself just before making a similar mistake.

Well, here's the solution:

$ touch AAA
$ chmod a-w AAA

As long as I don't use rm -f, a stray * parameter won't wipe out
my files before I have a chance to say no. I don't know why I
hadn't thought of it before!
