I am using tmux and zsh.
When I am outside tmux, zsh is customized with some Manjaro settings, as per the .zshrc
# Use powerline
USE_POWERLINE="true"
# Source manjaro-zsh-configuration
if [[ -e /usr/share/zsh/manjaro-zsh-config ]]; then
source /usr/share/zsh/manjaro-zsh-config
fi
# Use manjaro zsh prompt
if [[ -e /usr/share/zsh/manjaro-zsh-prompt ]]; then
source /usr/share/zsh/manjaro-zsh-prompt
fi
# Use ssh-agent
if [[ -e /home/marcosh/ssh-agent.zsh ]]; then
source /home/marcosh/ssh-agent.zsh
fi
source /usr/share/nvm/init-nvm.sh
When I am inside tmux though, the customizations are missing, eventhough it is using zsh. This is my .tmux.conf
set-option -g history-limit 50000
# sane scrolling
set-option -g mouse on
set -ga terminal-overrides ',xterm*:smcup#:rmcup#'
# new pane on same folder
bind '"' split-window -c "#{pane_current_path}"
bind % split-window -h -c "#{pane_current_path}"
# use zsh instead of bash
set -g default-command /usr/bin/zsh
What should I do to get the same zsh configuration both when inside and outside tmux?
The problem is tmux is not rendering the UTF-8 characters from the manjaro config properly.
To solve this use:
tmux -u
From the tmux manpage:
-u Write UTF-8 output to the terminal even if the first
environment variable of LC_ALL, LC_CTYPE, or LANG that
is set does not contain "UTF-8" or "UTF8". This is
equivalent to -T UTF-8.

Hello I would like to load multiple environments from different files. For example:
First File builds a session with 1 window and 3 panes.
Second File builds a session with 2 windows first window with 2 panes and second window with one pane.
Like:
tmux -f /path/to/file/basic.conf a
and then after detaching from the first session, i would like to load the same way the other enviroment.
tmux -f /path/to/file/scripting.conf a
but when i fire the second command i will attach to the first session (basic.conf).
But i would expect that when I fire the second script I would attach to the second session.
And tmux ls list only one session.
(The conf files by itself are running with no problem)
How is it possible to have multiple session build trough differnt conf files with tmux, and only with tmux no tmuxinator no tmuxp or anything else?
Or should i have one big conf file which builds everything that now is in muliply conf files?
basic.conf
SESSION_NAME="basic"
FIRST_WINDOW="shells"
SECOND_WINDOW="console"
source ~/.tmux.conf
new-session -s $SESSION_NAME -n $FIRST_WINDOW -d
split-window -h -t $SESSION_NAME
split-window -v -t $SESSION_NAME
new-window -n $SECOND_WINDOW -t $SESSION_NAME
select-window -t $SESSION_NAME:0.0
scripting.conf
SESSION_NAME="script"
FIRST_WINDOW="editor"
SECOND_WINDOW="console"
source ~/.tmux.conf
new-session -s $SESSION_NAME -n $FIRST_WINDOW -d
split-window -v -p 5 -t $SESSION_NAME
send-keys -t $SESSION_NAME:0.0 'cd ~/Code' C-m
send-keys -t $SESSION_NAME:0.0 'vim' C-m
send-keys -t $SESSION_NAME:0.1 'cd ~/Code' C-m
send-keys -t $SESSION_NAME:0.1 C-l C-m
new-window -n $SECOND_WINDOW -t $SESSION_NAME
send-keys -t $SESSION_NAME:1 'cd ~/Code' C-m
select-window -t $SESSION_NAME:0
I think I found a solution by myself.
The command:
tmux -f /path/to/file.conf a
should only be used when you would like to load another tmux config file instead of the default one.
If you like to start multiple sessions , which are preconfigured in files, then you have to do something like this:
tmux source-file -q .dotfiles/tmux/enviroments/basic.conf && tmux attach -t basic
Perhaps there is a better solution, but for now this solves my problem.
P.S. i made a little function to load the files less complicated.
function muxload(){
if [ -f ~/.dotfiles/tmux/enviroments/$1 ]; then
tmux source-file -q ~/.dotfiles/tmux/enviroments/$1 && tmux attach -t $1
fi
if [ -f ~/.dotfiles/tmux/enviroments/$1.conf ]; then
tmux source-file -q ~/.dotfiles/tmux/enviroments/$1.conf && tmux attach -t $1
fi
}
run it like this:
muxload {name_of_conf_file}
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})"
I just installed tmux on my new MacBook Pro, and am running into the following issue.
When I create a new window via the command tmux new-window I get a new window with the same working directory as the session I'm creating from. This is the behavior I expect/desire.
When I create a new window using C-b C-c, I get a new window in my home directory.
Why are my shortcut keys giving me different behavior/how do I make them use the same directory?
Since Tmux 1.9 you should use the -c option in order to open a new working directory of the current pane.
tmux new-window -c '#{pane_current_path}'
Add this to your tmux.conf:
bind c new-window -c '#{pane_current_path}'
Note: It is also possible that you will have to exit all running instances of the TMUX server before any changes to the .tmux.conf file will be loaded.
If you also want split windows in the current directory, you can add this to tmux.conf:
bind "\"" split-window -c '#{pane_current_path}'
bind "\%" split-window -h -c '#{pane_current_path}'
The quotes should not be in tmux.conf; at least not for tmux 2.1:
#
# open split panes in the current directory
#
bind-key \" split-window -c '#{pane_current_path}'
bind-key \% split-window -h -c '#{pane_current_path}'
I like to call :clear-history on panes with a huge scrollback. However, I want to script a way to send this command to all the panes in the various windows.
I know how to send a command to all the windows, courtesy of this question, but how do I send a command to all the panes of which window as well?
send-keys and synchronize-panes from the tmux manpage come to mind, but I'm not sure how to marry them together. But maybe there is a simpler way to do this.
Extra Observations:
Thinking about this a little bit, tmux list-panes -a seems to list all the panes in the current session. Pretty useful to start off with. Where do I go from here?
Have you tried following in tmux window with multiple panes
Ctrl-B :
setw synchronize-panes on
clear history
A bit late to the party but I didn't want to set and unset synchronize-panes just to send one command so I created a wrapper function around tmux and added a custom function called send-keys-all-panes.
_tmux_send_keys_all_panes_ () {
for _pane in $(tmux list-panes -F '#P'); do
tmux send-keys -t ${_pane} "$#"
done
}
I also create a wrapper around the tmux command to simplify calling this function (for convenience). The wrapper and the above code are all here.
This allows me to run tmux send-keys-all-panes <command> or tmux skap <command to send <command> to all panes.
Note that tmux is aliased to my wrapper function tmux_pp.
Update June 2019
Quick illustration on how to configure your own binding for synchronize panes.
Added the following into my tmux.conf (the comments certainly apply to my overall configuration):
# synchronize all panes in a window
# don't use control S, too easily confused
# with navigation key sequences in tmux (show sessions)
unbind C-S
bind C-Y set-window-option synchronize-panes
Now, I can toggle the ability to synchronize commands across multiple panes with <C-a><C-y>.
(Yes, I remapped the bind key to Ctrl a).
my tmux version is 1.9a, and this works for me, one key is enough for both on and off
bind-key X set-window-option synchronize-panes\; display-message "synchronize-panes is now #{?pane_synchronized,on,off}"
None of the above answers worked for me (tmux v2.3), but this did, from the bash command line:
for _pane in $(tmux list-panes -a -F '#{pane_id}'); do \
tmux clear-history -t ${_pane} ; done
A more generalized script, for tmux commands other than 'clear-history' would just replace that element with a parameter, eg. $1. Do be careful if you intend to write a script to handle a series of tmux commands, as "-t ${_pane}" will need to be applied to each.
Note that the -a parameter to tmux list-panes is required to cover all panes in all windows in all sessions. Without that, only panes in your current tmux window will be affected. If you have more than one tmux session open and only want to apply the command to panes within the current session, replace -a with -s (It's all in the tmux man page).
I haven't the mod points to comment directly on each of the above answers, so here's why they weren't working for me:
The problem that I had with #shailesh-garg 's answer was that the sync affected only commands issued within the panes, not tmux commands issued using Ctrl-B : which are outside the panes.
The three problems that I had with #kshenoy 's answer were that:
it sends keystrokes to within a pane, not to the tmux operation
of that pane, so for instance, if one had a bash shell running in
the pane and one used the script to send "clear-history", those
would be the keystrokes that would appear in the bash command-line.
A work-around would be to send "tmux clear-history" or to pre-pend
"tmux " to "$#", but I haven't edited the answer because of my other
problems with the answer;
I couldn't figure out how to send a
new-line character without literally breaking the line;
Even when I did that, sending "tmux clear-history" had no effect.
If you want to send your command to every pane in every window in every session, add this to your .bashrc:
send_command_to_every_pane() {
for session in `tmux list-sessions -F '#S'`; do
for window in `tmux list-windows -t $session -F '#P' | sort`; do
for pane in `tmux list-panes -t $session:$window -F '#P' | sort`; do
tmux send-keys -t "$session:$window.$pane" "$*" C-m
done
done
done
}
You can then use it like this:
send_command_to_every_pane source ~/.bash_profile
Change "$*" to "$#" if you want that behavior, but in my experience this is what you want.
tmux send-keys -t <session id> <command> C-m
Replace the "session id" and "command" accordingly.
This is my utility function to do it, only executing the command when there there is nothing running in the pane.
#!/bin/bash
_send_bash_command_to_session() {
if [[ $# -eq 0 || "$1" = "--help" ]] ; then
echo 'Usage: _send_bash_command_to_session $session_name what ever command you want: '
return
fi
input_session="$1"
input_command="${#:2}"
for _pane in $(tmux list-panes -s -t ${input_session} -F '#{window_index}.#{pane_index}'); do
# only apply the command in bash or zsh panes.
_current_command=$(tmux display-message -p -t ${input_session}:${_pane} '#{pane_current_command}')
if [ ${_current_command} = zsh ] || [ ${_current_command} = bash ] ; then
tmux send-keys -t ${_pane} "${input_command}" Enter
fi
done
}
tmux_set_venv() {
_current_session=$(tmux display-message -p '#{session_name}')
_send_bash_command_to_session ${_current_session} workon $1
}
Example targeting a session called dev, enabling a python virtualenv in all panes that are in bash or zsh, avoiding executing the command in panes with vim or any other executable:
_send_bash_command_to_session dev workon myvirtualenv
or easier to remember: to do it in the current session:
tmux_set_venv myvirtualenv
Find my configuration file with this function.
You can combine synchronize-panes and send-keys in a single shortcut to send commands to all the panes:
Predefined tmux command clear-history:
bind-key C set-option -w synchronize-panes on\; clear-history \; set-option -w synchronize-panes off
Prompt an arbitrary tmux command:
bind-key p command-prompt -p "Panes command: " "set-option -w synchronize-panes on; %% ; set-option -w -u synchronize-panes"
Prompt an arbitrary shell command:
bind-key p command-prompt -p "Panes command: " "set-option -w synchronize-panes on; send-keys %%\\n ; set-option -w -u synchronize-panes"
By default, byobu uses tmux as backend. It's a wrapper that make things much easier:
Shift+F9:
Ctrl+F9:
Shift+F1
Admittedly only semi-related, I found I could make the status background red when I toggle synchronize-panes so it's obvious when I switch back to a window with an unknown synchronize-panes state:
bind-key C-x setw synchronize-panes on \; set-window-option status-bg red \; display-message "pane sync on"
bind-key M-x setw synchronize-panes off \; set-window-option status-bg default \; display-message "pane sync off"
I started using tmux recently and things are good except for the fact that tmux prints out my last run command before output, e.g.:
~ $ pwd
pwd/Users/me
You can see that it put "pwd" before the directory there, which is annoying.
My shell(zsh) doesn't do this when I run commands outside of tmux.
show-environment -g doesn't reveal any weird options being passed to zsh or anything: SHELL=/bin/zsh
I read through the manpage and Googled around but I can't find anything.
Thanks for any help!
Figured it out -- needed to change my ~/.tmux.conf to have a different TERM(xterm instead of screen-256color):
# act like vim
setw -g mode-keys vi
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R
bind-key -r C-h select-window -t :-
bind-key -r C-l select-window -t :+
# act like GNU screen
unbind C-b
set -g prefix C-a
# look good
#set -g default-terminal "screen-256color"
set -g default-terminal "xterm"
set -g status "off"
