List all installed Linux kernel images:
dpkg --list | egrep -i --color 'linux-image|linux-headers'

Remove a single image:
apt-get --purge remove linux-image-...

Remove all:
apt-get purge $(dpkg --list |egrep 'linux-image-[0-9]' |awk '{print $3,$2}' |sort -nr |tail -n +3 |grep -v $(uname -r) |awk '{ print $2}')

  ~.  - terminate session
  ~B  - send a BREAK to the remote system
  ~R  - Request rekey (SSH protocol 2 only)
  ~#  - list forwarded connections
  ~?  - this message
  ~~  - send the escape character by typing it twice
(Note that escapes are only recognized immediately after newline.)

This is a tweak of https://github.com/mislav/dotfiles/blob/master/bin/tmux-vim-select-pane
which is linked from https://github.com/christoomey/vim-tmux-navigator as a possible fix for the vim integration.

I couldn't get the original one to work right on tmux 1.8 so I fixed it up.

These go into tmux config file:

bind-key -n C-h run-shell "~/tmux-vim-select-pane -L"
bind-key -n C-j run-shell "~/tmux-vim-select-pane -D"
bind-key -n C-k run-shell "~/tmux-vim-select-pane -U"
