That should do it.

    startx

would be one way to go, as `cat` will continue its job until it get killed. And
then when you reboot, you can access the file (which hopefully didn't end up
corrupted). Maybe `journalctl -k -b -1` will contain all the information as
well (given that the previous boot, was one that froze)?
