A jump-to-session tmux shortcut. With `<prefix> S` a prompt is shown to enter a session name. If no name is given, switches back to the previously attached session. Session name can be a partial string that the session starts with, as long as it's unique.

tmux-switch-session.sh

#!/usr/bin/env bash
set -e

if [[ -z $1 ]]; then
  tmux switch-client -l
else
  tmux switch-client -t "$1"
fi

tmux.conf

# switch to a session that start with the given name
bind S command-prompt -p session: "run-shell 'tmux-switch-session \"%%\"'"

Thanks for posting this, I incorporated the idea into a script that allows one to switch to / attach / create a given session easily: https://github.com/faceleg/dotfiles/blob/master/addons/tmux/scripts/switch-create-attach.sh
