Although, you do a sleep 10 after the process has finished starting
which is a bit pointless, the command after 'ls' won't be executed
until 'ls' has terminated. You would have to do 'ls &' to detach
that process from the script. This is the sort of thing that a=20
proper scripting language such as python would do much easier ;)

Keep us informed as to if it works (and what the hell it's for)
I assume it's some sort of stress testing??

Have fun,
Will
