Usage: $0 [-s SERIAL]
This tool will start ssh on your connected Ubuntu Touch device, forward a local
port to the device, copy your ssh id down to the device (so you only have to log
in once), rsync down your bash config so you get any nice prompt & aliases you
might be used to from your host bash config, and then finally sshs into the
device through the locally forwarded port.
This results in a very nice shell, which for example can display the output of
'top' at the correct terminal size, rather than being stuck at 80x25 like 'adb
shell'
Like ssh-copy-id, this script will push down the newest ssh key it can find in
~/.ssh/*.pub, so if you find the wrong key being pushed down, simply use 'touch'
to make your desired key the newest one, and then this script will find it.
