[supplies expanded which script]

I saved your script as I thought it was an interesting piece of work, but
I will point out a couple of problems:

1) The easy one was my (Dynix's) version of sh didn't like your syntax for
test(1), so I used ksh.

2) If you do (your script is called wh):

wh wall                 # you get:
wall not found

Similarly, w/ the system supplied which:

which wall              # you get:
no wall in . /hydra9/gt01/gt0178a /usr/local/bin /usr/ucb /bin /usr/bin /usr/att/bin /usr/att/usr/bin

which is of course my path. Finally, the system supplied (at least for me)
whereis gives:

ll `whereis wall`       # you get:
wall: not found
-rwxr-x---  1 root        20480 May 21  1988 /bin/wall*
-r--r--r--  1 root          984 May 21  1988 /usr/man/man1/wall.1

Ignore the 1st line, unless it is the only one. Obviously wall is failing
the executable test in the 1st 2 commands. Moral - don't stick to one tool
(there are lots of things whereis can't find).
