Don't leave your terminal idle around here:
 
% whoami
joe
% cd ~fred
% ls -lasFg .plan
   1 ----r--r--  1 fred     cs101           9 Feb 15 16:20 .plan
% cat .plan
Kick me!
% exit
 
 
Explained for the UNIX novice;  fred cannot read the `Kick me!' sign on his
account (which everyone else can), because he doesn't have read access to
his .plan.
