Reboot Windows system immediately

Using shutdown command, specifying wait of 0 seconds:

> shutdown -r -t 0

Reboot Linux system immediately

Getting dos2unix on Ubuntu

To get the tools onto the box, use:

> sudo apt-get install tofrodos

For Ubuntu 10, dos2unix does not exist; the tools fromdos and todos are defined instead. So, either add aliases:

> alias dos2unix=fromdos

or a link:

> ln -s fromdos dos2unix
