# It happens every so often on Arch Linux, that the kernel is updated and you have to reboot in order
# to being able to load the new kernel modules. This can lead to a situation where you are not able
# to mount filesystems, start docker, etc. because the old running kernel can not load the new modules.

# If you want to defer the reboot and still want to load some kernel modules, you can re-install the
# old kernel like this:

sudo pacman -U /var/cache/pacman/pkg/linux*-$(uname -r | grep -o "^.*-[0-9][0-9]*")-x86_64.pkg.tar.xz

Sometimes another client restricts the screen size of the current session.
The following command will quickly kill all other tmux clients from the session.

  tmux list-clients -t $(tmux display-message -p '#S') -F '#{client_tty}' | grep -v $(tmux display-message -p '#{client_tty}') | xargs --max-args 1 tmux detach-client -t

Add it to ~/.tmux.conf to have it as "C-b k" shortcut:

  bind k neww "tmux list-clients -t $(tmux display-message -p '#S') -F '#{client_tty}' | grep -v $(tmux display-message -p '#{client_tty}') | xargs --max-args 1 tmux detach-client -t"
