What waked up my computer?

I want to know if there is a command or program that shows the reason of the last wakeup from suspend.

In windows exists a builtin command which shows the last wakeup reason, for example the keyboard or mouse, or via WOL.

The thing is that it happened already 2 times to find my computer awake in the morning when I clearly put it to sleep at night.

/var/log/pm-suspend.log:

Tue Oct 22 23:50:24 EEST 2013: performing suspend
Wed Oct 23 08:24:11 EEST 2013: Awake.
Wed Oct 23 08:24:11 EEST 2013: Running hooks for resume

/var/log/syslog

dmesg

PS: Default 13.10 installation, WOL enabled, but I don't think this is a problem since I used WOL before (with Archlinux and SuSe) and it only woke when I told it to do so.

After investigating more, the fault was caused by my wireless mouse. If I put the computer into sleep and then moved the mouse, the computer would wake.

The solution was adding echo "disabled" > /sys/bus/usb/devices/3-7/power/wakeup in /etc/rc.local for it to run every time I power my computer.

That tells the usb port on which I have my EDR transmitter to disable the option of waking up via mouse.

Simple and clean.
