             As root, I made a text file (named  t ) that did something like
                        echo  $USER   |   tee  xx
and then had it set user-id (I did 'chmod  4755  t').  As a plain user, I 
made a directory that only  root  can write my current directory and then 
invoked  t  (by giving a path-name to it).  It reported that the  USER   was 
the plain user and couldn't write into the directory.  It appears that the 
set user-id didn't work, but I also checked  t  with  ls -l  and the 
permissions were   rwsr-xr-x , exactly like that of  passwd  and  xterm  
(except maybe for the write permission of the owner).
            How do I get set user-id to work?
