Yes I will straight away. Now lets see.....

-rwx--x--x   1 bin      bin         9525 Apr 13  1987 /bin/cat*

Now if I write a shell script called 'cat' such as:

#!/bin/sh
if [ $# = 0 ] 
then
	dd bs=512 2> /dev/null
else
	for i in $*
	do
		dd if=$i bs=512 2> /dev/null
	done
fi

(apologies for my shell programming if its wrong)

-rwx--x--x   2 bin      bin        47228 Jul 13  1988 /bin/sh*

Ok, so my super-duper shell script should work brilliantly for cat.
Ok, it'll take longer to load + execute, and on some machines i can't
exec() it, but I can rewrite my code to get round that can't I?

All for 9k's worth of disk space. Sigh, I don't know, some people.....

Dylan.

p.s. Sorry, I forgot the documentation too. On my machine, that comes to
an extra 1.5k. Even more savings!!!!!
