I'm trying to become more proficient with tmux, but I ran into ( what seems to me ), a weird issue. Here's my tmux.conf:
1 TERM=screen-256color
2 set-option -g default-terminal $TERM
3
4 TMUX_COLOUR_BORDER="colour237"
5 TMUX_COLOUR_ACTIVE="colour231"
6 TMUX_COLOUR_INACTIVE="colour16"
7
8 set-window-option -g window-status-activity-bg $TMUX_COLOUR_BORDER
9 set-window-option -g window-status-activity-fg $TMUX_COLOUR_ACTIVE
10 set-window-option -g window-status-current-format "#[fg=$TMUX_COLOUR_ACTIVE]#I:#W#F"
11 set-window-option -g window-status-format "#[fg=$TMUX_COLOUR_INACTIVE]#I:#W#F"
12
13
14 set -g prefix C-a
15
16 bind-key o split-window -v
17 bind-key e split-window -h
18
19 bind-key w kill-pane
I'm trying to copy paste between two panes. So, I hit Ctrl-a-[ , and then Ctrl-space. The thing is, I don't see a visual selection of the block, and alt-w also does not work ( since I guess it's not even entering copy mode ). Is there an obvious error in my tmux.conf? Can you spot what I'm doing wrong?
tmux has an option, mode-keys, you can find it in man page.
default is emacs, but if your $EDITOR is vim/vi, tmux will use vi.
So the key binding will be in vi mode.
E.g. your Alt-w won't work, it is emacs binding. you can see a table of key-binds in tmux man page.
some related to your question:
Function vi emacs
Copy selection Enter M-w
Start selection Space C-Space
so you should go with the vi-mode keys.
I used vim mode too, and did a little customization (to make it same as vim) in my tmux.conf, maybe you could give it a try:
bind-key -t vi-copy 'v' begin-selection # Begin selection in copy mode.
bind-key -t vi-copy 'C-v' rectangle-toggle # Begin selection in copy mode.
bind-key -t vi-copy 'y' copy-selection # Yank selection in copy mode.
In case it helps, I had a correct tmux configuration (with vi like settings for selection & copy/paste) but needed to set these two environment variables in my .zshrc file (using Zsh & Neovim):
export EDITOR='nvim'
export VISUAL='nvim'

Is there a way of displaying the currently running command (e.g. for situations where the script runs for days and you wish to retrieve the running parameters) as the tmux window name?
I.e
$ python train_net.py --lr 50 -> would cause the window name to change to python train_net.py --lr 50 instantly?
You can change tmux default config file. Usually it is in your home folder: ~/.tmux.conf. Add following lines to it:
set-option -g status-interval 1
set-option -g automatic-rename on
set-option -g automatic-rename-format '#{pane_current_command}'
You can change automatic-rename-format to any thing you like. pane_current_command means the current running command.
Then restart your tmux sessions or:
Ctrl+b then :source-file ~/.tmux.conf inside a tmux session to re read tmux config file.
Pay attention that this will automatically rename your tab if you haven't set a name for it manually, if you renamed it manually it won't make change.
For future references:
In ~/.tmux.conf add:
set-option -g status-interval 1
set-option -g automatic-rename on
set-option -g automatic-rename-format "#(ps -f --no-headers --ppid $(tmux display-message -p #{pane_pid}) | awk '{ print substr($0, index($0,$8)) }') "
set-option -g history-limit 3000
Then inside a tmux console ctrl+b :source-file ~/.tmux.conf to reload
Suddenly my tmux started with error .tmux.conf:41: usage: bind-key [-cnr] [-T key-table] key command [arguments]
on that line in tmux.conf was bind-key -t vi-copy v begin-selection
I suppose, the problem is with -t key, which is not predicted by bind-key command.
But it was working!
The different types of key table were integrated together and the -t flag dropped several years ago. Copy mode commands are now sent using send -X and the new table is called copy-mode-vi.
So your example becomes:
bind-key -Tcopy-mode-vi v send -X begin-selection
I just update to tmux 2.1(OS X10.11.3 Terminal.app), and my .tmux.conf（accroding to http://joehanchoi.com/quick-fixes-for-tmux-2-1-on-osx/）
set-option -g mouse on
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
but the problem is after I start tmux, the mouse pointer becomes a plus: +， and I cannot copy/paste anymore.
And right click on Terminal does not work, no popups
How to solve this?
There are two factors:
Terminal.app in El Capitan recognizes (some of) xterm's escape sequences for the mouse.
tmux 2.1 has some changes — for the (xterm) mouse protocol
This was discussed extensively in Mouse scrolling in tmux 2.1 on OSX no longer auto-starts #145 , but no one suggested a different configuration than the one you are using.
I am using tmux in a ssh session.
I am using multiple panes and windows.
I have mouse-mode enabled which works great so far.
When I select text it gets automatically copied to the tmux-buffer and the window jumps to the end.
So if i scroll up and click on something it jumps to the end...
When I switch between panes a copy command is triggered and the output goes to the end.
I really dislike this behaviour and I'd rather have to press a button to copy or click q to finish copy mode or something.
Is it possible to disable auto-copy // auto jump to the end on mouse button release?
I am running tmux 2.0 on the server through ssh. In Terminator on the client.

As of tmux 2.5 you should use
unbind -T copy-mode-vi MouseDragEnd1Pane
I'd say the easiest way nowadays is to just use the tmux-yank plugin and add the yank_action configuration option:
# ~/.tmux.conf
set -g #yank_action 'copy-pipe' # or 'copy-pipe-and-cancel' for the default
Additionally, tmux-yank also manages for you the differences between OS clipboards (Linux, macOS, WSL) and adds some very useful shortcuts for copying the current command line content and cwd. Highly recommended.
i was able to get mouse selection to stop jumping to the bottom in tmux (version 2.2) by adding the following to my ~/.tmux.conf:
setw -g mouse on
setw -g mode-keys vi
unbind -t vi-copy MouseDragEnd1Pane
caveat: this has the side effect of turning on vi mode.
i found this issue to be relevant, and found the configuration above in these dotfiles.
The following worked for me. Thanks to #stagebind on github!
For vi-mode config, https://github.com/tmux/tmux/issues/140#issuecomment-321144647:
unbind -T copy-mode-vi MouseDragEnd1Pane
For non vi-mode config, https://github.com/tmux/tmux/issues/140#issuecomment-302742783:
# 2.4+
unbind -T copy-mode MouseDragEnd1Pane
# 2.2 - 2.3
unbind -t vi-copy MouseDragEnd1Pane
Took me some time to get the correct answer.
I am also using Alacritty and cannot enable copy on mouse select because of an issue with MouseDragEnd1Pane as described in: https://github.com/jwilm/alacritty/issues/1002.
Selecting the text with the mouse and then if I need copy it using the key y works for me with this config:
bind -T copy-mode-vi y send -X copy-pipe "reattach-to-user-namespace pbcopy"\; display-message "copied to system clipboard"
Complete config for copy and pasting with mouse and vi key binding support looks like this:
set-option -g default-command "reattach-to-user-namespace -l bash"
set -g mouse on
bind P paste-buffer
bind-key -T copy-mode-vi v send-keys -X begin-selection
bind -T copy-mode-vi y send -X copy-pipe "reattach-to-user-namespace pbcopy"\; display-message "copied to system clipboard"
bind-key -T copy-mode-vi r send-keys -X rectangle-toggle
## don't jump to bottom on mouse select - when vi-mode enabled - 2.4+
#unbind -T copy-mode MouseDragEnd1Pane
## don't jump to bottom on mouse select - when vi-mode enabled - 2.2 - 2.3
#unbind -t vi-copy MouseDragEnd1Pane
## don't jump to bottom on mouse select - when vi-mode enabled
unbind -T copy-mode-vi MouseDragEnd1Pane
I am using OS X.
as of tmux 2.2 the feature copy-selection -x is available. With the following options tmux stays in copy mode after selecting. Choose the one that fits your mode setting.
bind-key -t vi-copy MouseDragEnd1Pane copy-selection -x
bind-key -t emacs-copy MouseDragEnd1Pane copy-selection -x
Looks like upgrading to tmux 2.1 might solve your problem.
Reasonable mouse support in tmux
In version 2.1 they changed mouse-mode, mouse-select-window/pane etc with single mouse switch. Mouse actions now generates key events that can be mapped as ordinary keys.
I am running tmux (version 1.9a) on a Mac OS X 10.6.8 with iTerm 2.
My default shell is tcsh, and I have several alias (and path, environment variables) defined in my .tcshrc file.
The problem is that all the alias are not defined when I run tmux, although I set tmux to run with the tcsh shell by default.
Addition: On the other hand the environment variables set in my .tcshrc are correctly passed in tmux. It seems a problem related just to alias...
Below my .tmux.conf
# copy and paster
set-option -g default-command "reattach-to-user-namespace -l tcsh"
# Define the default shell
set-option -g default-shell /bin/tcsh
# Avoid problems with alias defined in .tcshrc
set-option -g default-command $SHELL
set-option -g default-command "source .tcshrc"
# look good

Apparently the issue was solved by keeping the line
set-option -g default-command "reattach-to-user-namespace -l tcsh"
while erasing the lines
# Define the default shell
set-option -g default-shell /bin/tcsh
# Avoid problems with alias defined in .tcshrc
set-option -g default-command $SHELL
set-option -g default-command "source .tcshrc"
And restarting iTerm2 (no source or rehash did the job).
This would be because when you launch a standard shell from the terminal, it's a login shell, but with the option you've set for tmux, it's just an additional shell.
This line:
set-option -g default-command $SHELL
actually causes it to launch as a non-login shell. You've probably got some code blocked off with:
if($?loginsh) then
...
endif
which means that it doesn't get invoked in that case.
If you change the option to:
set-option -g default-command "$SHELL -l"
It will act like a login shell; alternatively remove the default-command, and in that case it will invoke the default shell as a login shell, which should have the same effect.
As an attempt at debugging this I started with a from-scratch .tcshrc containing:
echo tcshrc
if($?loginsh) then
echo login
endif
if($?prompt) then
echo prompt
endif
with set-option -g default-command "" (the default) I saw:
tcshrc
login
prompt
with set-option -g default-command "$SHELL" I see:
tcshrc
tcshrc
prompt
with set-option -g default-command "$SHELL -l" I see:
