Pressing ? within a tmux session lists out the available shortcuts.
But there are so many... how can one search for some text within those displayed shortcuts?
I figured it out. My tmux's default mode was in emacs. I just had to switch to Vi (which I am comfortable with). So all I had to do was:
set-window-option -g mode-keys vi
Using Fedora 25 and GNOME Terminal. I have used Tmux for a few years in Ubuntu with a long customized .tmux.conf file. Recently installed Tmux and Tmuxinator in Fedora.
When I open the Terminal. I see that the title is set to tom#localhost:~. When I create a new Tmux session such as tmux new -s panes. The title of the pane is still tom#localhost:~.
Inside the Tmux session. When I open a new window with name console like this new-window -n console. The title won't change to console and keeps saying tom#localhost:~.
I thought maybe tmux is not overriding the titles so I added this to the tmux.conf file:
set-option -g set-titles on
set -g terminal-overrides "xterm*:XT:smcup#:rmcup#"
That still doesn't do anything.
The Terminal settings. I have Profile/Command/When terminal commands set their own titles set to Replace initial title.
I cannot figure this out. What am I doing wrong here?
I am not exactly sure why it works. But this solves my problem.
Inside the .tmux.conf file I added the line set-option -g allow-rename off. At the top of the file I had the line set -g default -terminal "xterm". I removed this line.
When tmux opens, I would like it to use zsh instead of bash by default. How would I accomplish this?
From man tmux:
default-shell path
Specify the default shell. This is used as the login shell for new windows when the default-command option is set to empty, and must
be the full path of the executable. When started tmux tries to set a default value from the first suitable of the SHELL environment
variable, the shell returned by getpwuid(3), or /bin/sh. This option should be configured when tmux is used as a login shell.
So, in your tmux.conf:
# set shell
set -g default-shell /bin/zsh
and if you want you can add default command each time, when we start a new window:
# Retach userspaces
set -g default-command "reattach-to-user-namespace -l zsh"
You probably want zsh to be your default shell for most things, then (but this will not apply to cron). The following will make zsh your default shell, and you should then not need to tell tmux anything.
chsh -s /usr/bin/zsh
Note that some OSs still use /bin/zsh as the path to zsh.
If you prefer to set it individually for a session, but not for other (future) sessions, you can use
tmux new-session /bin/zsh \; set default-shell /bin/zsh
To allow scrolling a tmux pane with a mouse, I put the following in my ~/.tmux.conf file:
set -g mouse-mode on
However, nothing changes. When I scroll, it still scrolls outside of tmux. Why is this?
So this option has been renamed in version 2.1 (18 October 2015)
From the changelog:
Mouse-mode has been rewritten. There's now no longer options for:
- mouse-resize-pane
- mouse-select-pane
- mouse-select-window
- mode-mouse
Instead there is just one option: 'mouse' which turns on mouse support
So this is what I'm using now in my .tmux.conf file
set -g mouse on
As #Graham42 noted, mouse option has changed in version 2.1. Scrolling now requires for you to enter copy mode first. To enable scrolling almost identical to how it was before 2.1 add following to your .tmux.conf.
set-option -g mouse on
# make scrolling with wheels work
bind -n WheelUpPane if-shell -F -t = "#{mouse_any_flag}" "send-keys -M" "if -Ft= '#{pane_in_mode}' 'send-keys -M' 'select-pane -t=; copy-mode -e; send-keys -M'"
bind -n WheelDownPane select-pane -t= \; send-keys -M
This will enable scrolling on hover over a pane and you will be able to scroll that pane line by line.

Just a quick heads-up to anyone else who is losing their mind right now:
https://github.com/tmux/tmux/blob/310f0a960ca64fa3809545badc629c0c166c6cd2/CHANGES#L12
So that's just
:setw -g mouse
this should work:
setw -g mode-mouse on
then resource then config file
tmux source-file ~/.tmux.conf
or kill the server
Paste here in ~/.tmux.conf
set -g mouse on
and run on terminal
tmux source-file ~/.tmux.conf
As #Graham42 said, from version 2.1 mouse options has been renamed but you can use the mouse with any version of tmux adding this to your ~/.tmux.conf:
Bash shells:
is_pre_2_1="[[ $(tmux -V | cut -d' ' -f2) < 2.1 ]] && echo true || echo false"
if-shell "$is_pre_2_1" "setw -g mode-mouse on; set -g mouse-resize-pane on;\
set -g mouse-select-pane on; set -g mouse-select-window on" "set -g mouse on"
Sh (Bourne shell) shells:
is_pre_2_1="tmux -V | cut -d' ' -f2 | awk '{print ($0 < 2.1) ? "true" : "false"}'"
if-shell "$is_pre_2_1" "setw -g mode-mouse on; set -g mouse-resize-pane on;\
set -g mouse-select-pane on; set -g mouse-select-window on" "set -g mouse on"
Hope this helps
You can still using the devil logic of setting options depending on your current Tmux version: see my previous answer.
But since Tmux v1.7, set-option adds "-q" to silence errors and not print out anything (see changelog).
I recommend to use this feature, it's more readable and easily expandable.
Add this to your ~/.tmux.conf:
# from v2.1
set -gq mouse on
# before v2.1
set -gq mode-mouse on
set -gq mouse-resize-pane on
set -gq mouse-select-pane on
set -gq mouse-select-window on
Restar tmux or source-file your new .tmux.conf
Side note: I'm open to remove my old answer if people prefer this one
This line:
set -g mouse-mode on
in your ~/.tmux.conf file won't work.
For one thing, the proper setting is not mouse-mode, but mode-mouse.
Second, it only works on older versions of tmux (pre-version 2; you can run tmux -V to see what version you have, but you can also run man tmux to see if mode-mouse is a supported option).
And third, technically man tmux says to use the mode-mouse option with setw (set-window-option) and not with set (set-option), although I've seen it work with set (as well as setw).
These lines should work:
If your version of tmux is recent enough (that is, if tmux -V shows version 2 or newer), you can put this line in your ~/.tmux.conf file:
set-option -g mouse on
But if you use an older version of tmux, put these lines in your ~/.tmux.conf file:
set-window-option -g mode-mouse on
set-option -g mouse-resize-pane on
set-option -g mouse-select-pane on
set-option -g mouse-select-window on
Again, if you're not absolutely sure which line(s) to put in your ~/.tmux.conf file, run man tmux and search for mouse-mode, mouse-resize-pane, mouse-select-pane, and/or mouse-select-window. If you find them, then use those options (the ones for the older version of tmux).
Putting these lines in will allow you to use the mouse scroll wheel, it will allow you click on various panes to activate them, and it will allow you to resize panes just by clicking-and-dragging on their splitter separator.
You can also copy-and-paste using your mouse. However, you may notice that copying-and-pasting with your mouse may not work like it normally does on your console. To work around this, I've noticed that holding down the SHIFT key while using your mouse's copy/paste abilities makes them work normally again. (On MacOS, fn seems to work for me better than SHIFT.) Or you can learn tmux's approach to copy-and-pasting (which I do recommend).
A note on using tmux's native ability to copy/select/paste:
Personally, I feel that the vi keys make more sense to me than the default emacs keys (for example, it feels more natural to exit selection mode with vi mode's ENTER than with emacs mode's CTRL+w or ALT+w), so I have this in my ~/.tmux.conf file:
# For vi-like keys in copy/paste/selection mode:
set-window-option -g mode-keys vi
However, I've noticed that on older versions on tmux, this line won't work, unless I've also included the line:
set-window-option -g mode-mouse on
Good to know: Occasionally, when you're using the mouse's scroll wheel, you'll discover that your pane/screen appears to be frozen or locked up (it won't respond to keyboard input), and it's not clear what to do to unlock it.
It's not locked up. You're likely in tmux's selection mode. To get out of it, try one of these:
Hit ENTER. (Will likely work in vi mode.)
Hit ALT+w. (Will likely work in emacs mode.)
Hit CTRL+w. (Will likely work in emacs mode.)
Hit META+w. (Will likely work in emacs mode.)
Hit Esc. (Will likely work in emacs mode.)
Hit q. (Will likely work in vi mode, and may work in emacs mode as well.)
Ultimately, you can try hitting:
CTRL+w ENTER
or:
Esc q
Chances are, that will put you back in the normal mode where your keyboard is responsive again.
Using the mouse with vim:
I've discovered that putting this line in my ~/.vimrc file:
:set mouse=a
seems to work well with tmux, better than this line:
:set mouse=r
I can't really explain the difference; if you're a vim user, try them out and see which setting works best for you.
If you need to test out these tmux options, you may find yourself editing your ~/.tmux.conf file, exiting tmux, and then restarting tmux. This can become a tedious process, so if you want some work-arounds, here are some options:
Option1: After editing (and saving) your ~/.tmux.conf file, run this command (while in tmux):
CTRL+B :source-file ~/.tmux.conf ENTER
This will immediately apply the new settings in your ~/.tmux.conf file into your current tmux session, without the need to restart tmux.
Option 2: If you're in a tmux session, you can turn on/off options temporarily just for that session by running commands like these at the Unix shell prompt:
tmux set-option -g mouse on
tmux set-window-option -g mode-keys vi
Option 3: You can also temporarily turn on/off options in a tmux session with:
CTRL+B :set-option -g mouse on ENTER
CTRL+B :set-window-option -g mode-keys vi ENTER
Good luck, and have fun using tmux !
Try this. It works on my computer.
set -g mouse on
Ctrl + B and then set mouse. -g is not needed anymore.
it just happened on my Lion system, I am using zsh with tmux
normal in the zsh shell
double space in tmux screen
am I missing some config in zsh or tmux?
Start tmux with the -u option for unicode functionality. See this issue.
From man tmux:
-u
tmux attempts to guess if the terminal is likely to support UTF-8 by checking the first of the LC_ALL, LC_CTYPE and
LANG environment variables to be set for the string "UTF-8". This is not always correct: the -u flag explicitly
informs tmux that UTF-8 is supported.
If the server is started from a client passed -u or where UTF-8 is detected, the utf8 and status-utf8 options are
enabled in the global window and session options respectively.
I ran into this problem with zsh, byobu and tmux.
To fully solve it:
Add the following to ~/.zshrc:
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
Add -u after byobu-lauch in ~/.zprofile:
_byobu_sourced=1 . /usr/bin/byobu-launch -u
Add the following to ~/.byobu/.tmux.conf:
set-option -g utf-8 on
I had the same problem when I changed system language to English. When I use command locale all fields was empty. And when I set format language in preferences (Language & Region -> Advanced) to Russian - command locale was with filled values and in tmux it was ok.
