Don't want to flog a dead horse, but if I read the manpages right it seems that
-222
should be true only if the 'w' flag is on in all 3 positions, but
+222
will be true only if the 'w' flag is on in *any* of the 3 positions.

Is this right? Also, I didn't find any refernce to the shorthand +2. Perhaps it's one of those mystical osmosis things...:-)

My reading of the manual is that:
-222 examines bit 2 being on in all of the 3 areas
+2 examines bit 2 being on in all of the 3 areas
222 checks exact permissions 222

I could be mistaken, but -perm +2  has always worked for me.  I'll test it later.

Nope, and yes, am aware :)
