🔪 killing tmux

Now it's time to switch gears, we are onto a different part of our day and there are just too many sessions running and we need to clean up shop.


One viable option is to nuke the whole dang thing. I actually do this more than you might think.

tmux kill-server
Enter fullscreen mode Exit fullscreen mode

save and commit your work diligently before kill-server


A more reasonable option might be to kill a single session.

# kills the current session
tmux kill-session

# kills the session named scratch
tmux kill-session -t scratch
Enter fullscreen mode Exit fullscreen mode


Killing sessions one by one from the command line can be a bit tedious, and involve more keystrokes than necessary. Another option built right into tmux is choose-tree. By default choose-tree is bound to prefix+s, that's pressing control+b then s. Once you are in choose-tree, you can navigate around with your configured navigation scheme, press x to kill a session, or pane or window then y to confirm. You can also batch delete by tagging items with t, and killing them all at once with X.

fuzzy matcher

Here is my preferred way, using a fuzzy matcher. I recently improved this one by making it a popup and cleaning it up based on a repsonse,tmux-output-formatting by DJ Adams. I press prefix+k to bring up a kill-session menu.

bind k display-popup -E "\
    tmux list-sessions -F '#{?session_attached,,#{session_name}}' |\
    fzf --reverse -m --header=kill-session |\
    xargs -I {} tmux kill-session -t {}"
Enter fullscreen mode Exit fullscreen mode

note this is setup to multiple sessions all at once.
