unmount:: command not found

[transistortoaster]

Hello,
I was following the remastering steps from
http://www.knoppix.net/wiki/Knoppix_Remastering_Howto

and I can't do the "unmount /proc" from the "Leaving Chroot" section. I get an error from bash:
bash: unmount: command not found.
Any kind advice on what do to?
Thanks,
Frank

I figured this one out by myself:
The command is umount, not uNmount.
