Here's how to do that quickly - put this in an executable file called gen.ksh:

---------------------------
i=0
while (( $i < 10000 ))
do
        cat <<! > run.ksh
echo "All work and no play makes Jack a dull boy"
!
        cat <<! > runC.ksh
# All work and no play makes Jack a dull boy
echo "All work and no play makes Jack a dull boy"
!
        i=$(( $i + 1 ))
do
chmod oug+x run.ksh
chmod oug+x runC.ksh
-------------------------

Then execute "gen.ksh" which will generate "run.ksh". Now execute these commands:

time run.ksh
time runC.ksh

You MAY want to redirect stdout to stderr 8-). Obviously you can change the
"echo" lines to whatever you like.

Enjoy...
