Thanks for the help, but it still doesn't work:

$ sudo "echo 4 > /proc/acpi/sleep"
sudo: echo 4 > /proc/acpi/sleep: command not found

Don't be so silly! What rubbish are you writing? If you want to pass a
1 to acpi/sleep you will have to sudo the command that does it. The
redirection is in YOUR shell, not in roots!

If you want to start a root shell that does the echo, then

sudo sh -c "echo 4 > /proc/acpi/sleep"

but what's the point? Just do

echo 4 | sudo dd of=/proc/acpi/sleep

or zillions of other alternatives ! Why do you choose precisely the
only combinations of nonsense to use, instead of writing something that
makes sense!

<giggle> I just *love* it when a pretty darned experienced user makes a
comment. What is clear to Peter is a new revelation to most of us. Thanks
Peter.
