I am using tmux to manage multiple terminal windows. Currently I have 2 windows open with multiple panes. I know that I have to use the prefix (for me it is ctrl+a) to enter commands.

How can I close the session from inside of tmux? What command would close the session (all windows and panes) and tmux at the same time?


Press your prefix (e.g. Ctrl+A or B, which is the default) and then : and type kill-session, then hit Enter. This will, as the name of the command suggests, kill the session.


If you want to close session other than the current session (and hence keep tmux running; closing the current session as in @0xC0000022L's answer, also closes tmux even if other sessions are available), do the following in one of the tmux windows:

# tmux ls
keepMe: 1 windows (created Wed Jun 24 14:20:15 2015) [171x41]
otherSession: 1 windows (created Wed Jun 24 14:22:01 2015) [171x41]
3: 1 windows (created Wed Jun 24 14:23:28 2015) [171x41]

(assuming here that you're on keepMe session)
# tmux kill-session -t otherSession
# tmux kill-session -t 3

This deletes the "otherSession" or session number 3, and leaves tmux running, assuming you didn't have "otherSession" or number 3 session selected when you deleted them.

  • Or if you prefer using your prefix, ctrl + prefix followed by : and then type kill-session -t name or kill-session -t number. If you do this from within the session you want to kill reattach using tmux a. – Matijs Apr 14 '16 at 10:03

TMUX Prefix (e.g. ctrl+b) + :kill-session


tmux kill-session (could run either from the inside of a session or the outside)

Both styles of invocation can use the flags:

-t target-session destroys the given session
-a destroys all sessions but the given one or the one you are attached to

Running kill-session from the outside of TMUX kills the last session you were attached to. -a inverts that.

In the event, that you have more than one session running you could kill all sessions at once with: kill-server.

  • This is similar to the current accepted answer, can you go into a little more detail on why your answer is different? – Burgi Dec 29 '16 at 12:37

    No one pointed out, that you could close all sessions with the kill-server command. I also liked to provide a little more depth on the flags for kill-session. – FSchndr Dec 29 '16 at 14:34
  • +1: This answer is also the only one with the helpful -a to destroy all other sessions. – AaronDanielson May 24 '17 at 13:53
  • This is the better answer. I wish this were on the top of the answers... – Blaszard Jul 4 '18 at 11:31
