I'm working on a Linux server who is in a different time zone than me. How can I make tmux display, in the status bar, my local time, instead of the server local time (without messing up the server time)? For info, I'm using tmux 3.1

How can I attach to the the first tmux session **that has no attached clients** or, if there are no unattached sessions, create a new session and attach to that? (The use case is for a command for my terminal emulator to run when opening a new terminal window. I don't want it to create a new session each time I open a window, if there are detached sessions lying around. Nor do I want it to re-attach to the same named session every time, if there's already a window attached to that session. I want it to recycle existing unattached sessions but create new sessions when there are none unattached.)

The QA [how to set shortcut for 'copy mode'?](https://unix.stackexchange.com/questions/450184/in-tmux-how-to-set-shortcut-for-copy-mode) explains how to set a shortcut to tmux copy mode. My question is different, I want to change a shortcut within copy mode, in particular copy-mode-vi. This is part of my ~/.tmux.conf where I have set up copy mode: # Copy paste in tmux based on # https://www.rushiagr.com/blog/2016/06/16/everything-you-need-to-know-about-tmux-copy-pasting-ubuntu/ bind P paste-buffer bind-key -T copy-mode-vi v send-keys -X begin-selection bind-key -T copy-mode-vi y send-keys -X copy-selection bind-key -T copy-mode-vi r send-keys -X rectangle-toggle # Also copy to system clipboard bind-key -T copy-mode-vi y send-keys -X copy-pipe-and-cancel 'xclip -sel clip -i' # map copy mode to ctrl+alt+c bind-key -n 'C-M-c' copy-mode # map paste buffer to ctrl+alt+v bind-key -n 'C-M-v' paste-buffer I have my vim normal mode $ mapped to the m key (I use an azerty keyboard). How can I configure tmux's copy-mode-vi in a similar way so that the m moves to the end of line (i.e. $).

So I use ctrl + a (bound to a instead of b), and I try to ctrl + a and release then type in SHIFT + ' which is " so ctrl + a + " like the horizontal split should in theory work. When I do that I get a weird menu (I'm not sure what this menu is, why it pops up, I'm trying to figure out how to correctly get the horizontal split to work)

I'm trying to replicate some useful features from my work PC at home. At work, bash will helpfully autocomplete tmux "sub-commands": e.g. I type "tmux new-s" and bash autocompletes that to "tmux new-session" (I hope "sub-command" is the right term). **This doesn't happen on my home PC -- what can I do to set this up on my home PC?** I've looked around online and found some references to auto-complete *within tmux*, e.g. to auto-complete commands like move-window -- but that's not what I'm looking for. I also found reference to a feature called "bash complete" -- but on my work PC, I don't find any reference to tmux in my ~/.bash_completion file or my /etc/bash_completion.d/ directory. **Can someone please explain either where/how else my work PC might have set up its tmux "sub-command" autocompletion (so that I can refer/learn from a working example), or how I can/should set this up?** Interesting side-note: both my work and home PCs autocomplete git "sub-commands"; e.g. typing "git clo" autocompletes to "git clone". I didn't do anything specific to set that up -- for both git and tmux, all I did as far as setup was "sudo apt install git" and "sudo apt install tmux", respectively.

When I press Ctrl+b, W, tmux shows the list of all current windows and their panes. How can I kill a window and its panes from within this list view?

Recently I installed tmux on my Ubuntu 16.04. The terminal screen in tmux shows 256 color correctly however when I opened vim within tmux, the color was different from what it showed when it was run directly on the terminal. I tried to add set -g default-terminal "screen-256color" in my .tmux.conf file but the problem still exists. * my terminal screen in tmux:  * vim run directly on the terminal:  * vim run within tmux:  The output of echo $TERM; tput colors; tput longname * outside tmux:

xterm-256color
256
xterm

* with 256 colors inside tmux:

screen-256color
256
GUN Screen with 256 colors

According to the man page, if I run this command: tmux source-file ~/.tmux.conf tmux is going to execute the commands in ~/.tmux.conf. However if, for example, I add a key binding to tmux.conf, and later remove it, the key binding stays, even if I source the file (which is logical, since there's no actual command to execute for that binding). So I'm wondering, before sourcing the config, if there a way to somehow clear tmux's internal state (all binding, settings, etc.) so that it starts with the default one?

How can I write all the scrollback in a tmux session to a file? capture-pane can grab the current screen, but not the entire scrollback.

tmux keeps track of active sessions in a file, on my system this is in /tmp/tmux-1000/default. Recently I manually cleared everything in the /tmp directory, removing this session file. Normally, you can use tmux attach to reattach to a session. Active sessions can be listed using tmux ls. Because this file is gone, tmux doesn't know about any active sessions: $ tmux attach no sessions $ tmux ls error connecting to /tmp/tmux-1000/default (No such file or directory) Using top I can verify tmux is still running, along with the applications I had opened in that session. How can I reattach to this session, after I've removed the session file?

I just updated to Debian/Linux 9 (Stretch) and am in the process of setting everything up. So far I've only installed vim and tmux. My problem is that when I use the arrow keys, they return raw data/non escaped characters. - UP arrow returns: ^[[A - DOWN arrow returns: ^[[B - LEFT arrow returns: ^[[D - RIGHT arrow returns: ^[[C I am not able to go left or right on a line, or use up and down arrows to scroll through my previous commands/bash history ANYTIME I use tmux for ANYTHING.

When using "Power Off" action in Gnome if there are some GUI applications with unsaved changes (for example, text editor) there will be label "Some applications are busy or have unsaved work". I am looking for a way to set this "unsaved" status from command line. So I can integrate it into my workflow when I'm using tmux/neovim, to not accidentally power off PC when I have some sessions opened.

I'm running Ubuntu server (version 24.04.2 LTS). I'm quite happy with it. Sometimes I need longrunning processes, therefore I start them in a tmux session. But I have a small issue when I run tmux. In the .bashrc file, the .bash_improvements file is sources when $color_prompt is yes. This works, but ONLY if I run tmux from within my home folder. if [ "$color_prompt" = yes ]; then source .bash_improvements else PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ' fi unset color_prompt force_color_prompt When I start tmux from a different directory, then I receive the following error: -bash: .bash_improvements: No such file or directory. I understand the error, because the .bash_improvements file is indeed not available in that directory. I also can fix it by changing the default .bashrc file, but that doesn't feel right. How do I fix this in a structured way?

From time to time I saw my status bar rightmost few chars disappear. For instance, the intended one 11:40 to be 11:4 My .tmux.conf is as the following: # Set status bar set -g status-bg black set -g status-fg white set -g status-left '#[fg=green]#S' set -g status-right '#[fg=yellow]#(uptime | egrep -o "[0-9]+ users?, +load.*"|perl -pe "s| averages?||"), %H:%M' set -g status-left-length 20 set -g status-right-length 40 Any idea? Thank you.

Is there a way to select a Tmux Window by the number listed in the preview while in Sessions List view (activated with: C-b s)? In other words, how do I switch to window 3 (circled in red) in this screenshot?:  I am aware that I can switch windows directly (without going into Sessions List view) with: C-b [1-0]. The issue with that is that I often forget where my windows are and am helped by having a preview of their contents. I am also aware that I can expand the windows in Sessions List view or else load the Window List view with: C-b w to see a list of all windows. The issue with that is that you have to spend time expanding the list of windows or (if you launch the Windows List view) you can only see a preview of one window at a time. Edit: I attempted TechLoom's solution but it didn't work for me (see Gif)

I have put

set -g mouse on 
set -g mouse-select-pane on

in my .tmux.conf file and then I open tmux and create a new pane and I cant switch pane with mouse. is there something else I need to configure? I am using tmux 2.9 on Mac using zsh.

In a terminal, are there any shortcuts to jump to a previous/next prompt? Scrolling up and trying to find the start of a log slows down my workflow. I'm using iTerm on OSX, but this should be applicable to any Unix terminals. A solution in Tmux would help as well.

I'm having difficulty finding an explanation for allowing the OS default copy/paste capabilities (i.e. highlight a portion of text and then use standard shortcut or right-click menu) and allow mouse scrolling at the same time. Mouse mode turns on tmux's own copy/paste system, but leaving it off removes the mouse scrolling. As I'm switching between an IDE, browser, and terminal with tmux I would like the controls to be consistent between all of them. Is there a way to have the standard OS copy/paste controls while also allowing the mouse to scroll in tmux? _(Note: I originally asked, but deleted, this question on SO. I decided it was more appropriate here.)_

I am running tmux inside urxvt. I would like to select and copy text using the left mouse button and paste it using the middle mouse button -- I am very old school. I did get tmux-yank almost working but need to hit SHIFT+Mouse 1 Select doing the selection, then hit y… This is a lot of key presses. Anyone knows how I can get this simple behaviour working better?

Due to the change in Tmux2.1, I need to remap my mouse's middle click to tmux's paste: bind -T root MouseDown2Pane run -b "tmux paste-buffer" However, I also would like to enable using Ctrl (or Alt, Cmd) + middle click to paste the system's clipboard. This is what I have tried (failed) so far: bind -T root M+MouseDown2Pane run -b "pbpaste | tmux load-buffer -; tmux paste-buffer"
