from what I understand
set -g mouse-select-window on
Should allow me to click on a window in the status bar and go to that window. I put that in my tmux.conf file though and nothing happens when I click on a window. What am I doing wrong?
In my .tmux.conf I have the following:
set -g mode-mouse on
set -g mouse-select-window on
set -g mouse-select-pane on
Do you have the mode-mouse on setting?
On 2.1 this config got deprecated and the new option to allow all mouse support is:
set -g mouse on
This break the nice mouse scroll support, but can be enabled with this:
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'"

I heard much good about TMUX but so far I am just failing with the setup.
I would like to use the vi mode that allows you to copy with "SPACE" an "ENTER".
Currently I must use CTRL+SPACE and ALT+W.
I am running KALI 5.9.0 and TMUX 3.1c
When I run TMUX and check the setting it shows me the following:
$ tmux show -g status-keys
status-keys emacs
$ tmux show -g mode-keys
mode-keys emacs
My ~/.tmux.conf files looks like this:
set-window-option -g status-keys vi
set-window-option -g mode-keys vi
I also tried the following two:
setw -g status-keys vi
setw -g mode-keys vi
set -g status-keys vi
set -g mode-keys vi
I killed all tmux session and checked again but it seems as something is permanently overwriting my vi mode.
What am I missing?
I have this in my .bashrc, and when I run tmux everything's still in vi mode:
# use vi shortcuts in terminal
set -o vi
I would like to have tmux to automatically rename the window with the current working directory (cwd). As it is by default, it names the tab/window as the name of the current process, such as zsh or vim.
When I open a new window in tmux, the name is reattach-to-use-namespace and then it immediately switches to zsh.
I'm on OS X 10.10.2, I use zshell, and I have tmux 1.9a.
To be clear, I don't want the entire path in the name of the window, just the current directory, so for example, I want projectName, not /Users/username/Development/projectName.
If you want to see my current tmux.conf, here it is.
With tmux 2.3+, the b: format modifier shows the "basename" (or "tail") of a path.
set-option -g status-interval 5
set-option -g automatic-rename on
set-option -g automatic-rename-format '#{b:pane_current_path}'
The FORMATS section of man tmux describes other modifiers, such as #{d:} and even #{s/foo/bar/:}.
With tmux 2.2 or older, the basename shell command can be used instead.
set-option -g status-interval 5
set-option -g automatic-rename on
set-option -g automatic-rename-format '#(basename "#{pane_current_path}")'
Expanding on what Josef wrote, you can put the basename of the directory in the status using a shell snippet:
# be sure to see note* below
set -g window-status-format '#I:#(pwd="#{pane_current_path}"; echo ${pwd####*/})#F'
set -g window-status-current-format '#I:#(pwd="#{pane_current_path}"; echo ${pwd####*/})#F'
# status bar updates every 15s by default**, change to 1s here
# (this step is optional - a lower latency might have negative battery/cpu usage impacts)
set -g status-interval 1
*Note that what would be ${pwd##*/} is escaped to ${pwd####*/} since # has special meaning in the format string.
**See here for an example default tmux config.
Show the top N components
Showing just the basename generates too much ambiguity, but full paths are too much clutter, so I settled for:
the/last/path
instead of:
/a/very/long/the/last/path
or just:
path
.tmux.conf
set-window-option -g window-status-current-format '#[fg=white,bold]** #{window_index} #[fg=green]#{pane_current_command} #[fg=blue]#(echo "#{pane_current_path}" | rev | cut -d'/' -f-3 | rev) #[fg=white]**|'
set-window-option -g window-status-format '#[fg=white,bold]#{window_index} #[fg=green]#{pane_current_command} #[fg=blue]#(echo "#{pane_current_path}" | rev | cut -d'/' -f-3 | rev) #[fg=white]|'
Trick taken from: Remove part of path on Unix
If that still does not solve ambiguity, I go for:
bind-key -r w choose-window -F '#{window_index} | #{pane_current_command} | #{host} | #{pane_current_path}'
Tested on Tmux 2.1, Ubuntu 16.04.
To get the best of both worlds - window name is path when you're at a shell prompt, but name of executable when you're running something, try this:
set-option -g status-interval 1
set-option -g automatic-rename on
set-option -g automatic-rename-format "#{?#{==:#{pane_current_command},bash},#{b:pane_current_path},#{pane_current_command}}"
Replace "bash" with whatever shell you're using.
Adding this config to your ~/.tmux.conf file should work:
set-option -g window-status-current-format '#I:#{pane_current_path}#F'
set-option -g window-status-format '#I:#{pane_current_path}#F'
set-option -g status-interval 1
It depends however on your Tmux version. I wasn't able to make it work on 1.9a3 (in Cygwin) - but with Tmux 1.8 on Ubuntu (in Vagrant) it worked fine.
I use the following in ~/.tmux.conf to achieve this (working on OSX, zsh, tmux-2.3):
set -g automatic-rename-format '#{pane_current_path}'
set -g status-interval 5
You can set status-interval to 1 to make it respond faster to changing directories.
According to the changelog (https://raw.githubusercontent.com/tmux/tmux/master/CHANGES) this should work in tmux 1.9 and up.
Using ssh into a CentOS machine with tmux 2.3 the window name doesn't change until I press return in the new panel, not sure why that is happening.
Do something like this in a tmux session for zsh shell:
setopt PROMPT_SUBST
export PS1=$'\ek$(basename $(pwd))\e\\> '
If someone uses bash shell:
export PS1="\033k\$(basename \$(pwd))\033\\> "
You can add these commands in the shell initialization file on the condition the $TERM env variable is set to the value "screen"
I am using zsh hook for that
Add following in ~/.zshrc
precmd () {
if [ -n "$TMUX" ]; then
tmux set-window-option -q window-status-format "#[fg=cyan bg=cyan] | #[fg=white, bg=cyan] #I | ${PWD##/*/} #[fg=cyan, bg=cyan] | "
tmux set-window-option -q window-status-current-format "#[fg=cyan, bg=cyan] | #[fg=white, bg=cyan] #I | ${PWD##/*/} #[fg=cyan, bg=cyan] | "
fi
}
This doesn't strictly answer your question--it doesn't automatically rename an existing tmux session to the current working directory.
Rather, when creating a new session, it names that session after the current working directory.
Here's what I did:
to
~/.aliases
add
alias tm='tmux new -s `basename $PWD`'
Open a new terminal window and type:
tm
This now creates a new tmux session which is named after the current working directory.
Note: This relies on basename which does not exist in Windows.
I am sure that you want use this:
set -g status-left '#{pane_current_path} '
To change what you see in the window list you can specify a format when you define the key-binding for the chose-window function like this:
bind-key '"' choose-window -F "#{session_name} | #{window_name} - #{b:pane_current_path} (#{pane_current_command})"
tmux has a command mode that can be accessed via C-b : and I'm wondering if there is a way to alias commands in my .tmux.conf file like split-window to something I use more often like vsp in vim.
I know I can bind keyboard shortcuts with bind but can I alias commands as well?
tmux 2.4 adds the command-alias array option which does this, so for example you can do
:set -s command-alias[10] vsp='split-window -h'
And then you can use :vsp in the command-prompt just like you'd expect.
This doesn't appear to be possible as of tmux 2.0.
One thing you can do, however, is send commands to the enclosing tmux session from the shell. This means that you can, for example, create a bash alias that can split windows:
alias vsp="tmux split-window -h"
You can then run vsp from your bash prompt to split the tmux window vertically. Depending on your specific use case, this might help.
It's also worth noting that, if minimising typing is the goal, tmux commands can be shortened to their shortest unambiguous prefix: sp does the same thing as split-window.
There's a mod allowing not only alias but also create new commands in tmux: http://ershov.github.io/tmux/
For example:
proc vsp {args} { split-window -h {*}$args }
No external shell involved, no new processes spawned.
You can use bind. Here is an example alias for turning mouse-mode on and off:
bind m \
set -g mode-mouse on \;\
set -g mouse-resize-pane on \;\
set -g mouse-select-pane on \;\
set -g mouse-select-window on \;\
display 'Mouse mode ON'
bind M \
set -g mode-mouse off \;\
set -g mouse-resize-pane off \;\
set -g mouse-select-pane off \;\
set -g mouse-select-window off \;\
display 'Mouse mode OFF'
Now you can easily use Ctrl+B m to turn it on, and Ctrl+B M to turn it off (assuming Ctrl+B is your prefix)
Yep. Using bind-key in you tmux.conf. For example to split tmux windows use:
bind-key v split-window -v #C-b v to split vertically
bind-key h split-window -h #C-b h horizontal
If you don't want to use prefix (C-b) just add -n param:
bind-key -n C-right next # C - → to move to next window.
On Mac Mountain lion, tmux installed via Homebrew.
Some settings like the following doesn't work:
setw -g pane-base-index 1
set -g mouse-resize-pane on
set -g mouse-select-pane on
set -g mouse-select-window on
Then error:
/Users/millisami/.tmux.conf: 52: unknown option: pane-base-index
/Users/millisami/.tmux.conf: 53: unknown option: mouse-resize-pane
/Users/millisami/.tmux.conf: 55: unknown option: mouse-select-window
Whats wrong?
As rado said, tmux 2.1 doesn't support the individual mouse settings. It replaced them with a single setting, mouse which can be set with set -g mouse on in your ~/.tmux.conf.
As for the pane-base-index setting, Mark Nichols suggestion of:
# set window and pane index to 1 (0 by default)
set-option -g base-index 1
setw -g pane-base-index 1
worked for me on OS X 10.10.5 running tmux 2.1 installed via brew in iTerm 2.1.4.
# set window and pane index to 1 (0 by default)
set-option -g base-index 1
setw -g pane-base-index 1
set -g mode-mouse on
setw -g mouse-select-window on
setw -g mouse-select-pane on
It could be that you are using tmux 2.1, which doesn't support those anymore.
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.
