I'm trying to write a script that sets up a series of tmux panes within one window. Each pane wil have a separate program loaded into it, mimicking an IDE.
This is the script I'm running:
#!/bin/sh
tmux new-session -s Editor -n Desktop -d
# Set up main editor window
tmux select-window -t Editor:Desktop
tmux -u attach -t Editor
# Create splits
tmux send-keys -t Editor:Desktop 'C-b %' # 0
tmux send-keys -t Editor:Desktop 'C-b "' # 1
tmux send-keys -t Editor:Desktop 'C-b "' # 2
tmux send-keys -t Editor:Desktop 'C-b "' # 3
# Load programs into panes
tmux select-pane -t 0
tmux send-keys -t Editor:Desktop 'ccb' Enter
tmux send-keys -t Editor:Desktop 'vim' Enter
tmux select-pane -t 1
tmux send-keys -t Editor:Desktop 'ccb' Enter
tmux send-keys -t Editor:Desktop 'working_set --watch .' Enter
tmux select-pane -t 2
tmux send-keys -t Editor:Desktop 'ccb' Enter
tmux send-keys -t Editor:Desktop 'clear' Enter
tmux select-pane -t 3
tmux send-keys -t Editor:Desktop 'ccb' Enter
tmux send-keys -t Editor:Desktop 'npm start' Enter
This doesn't do as expected. Instead, it loads up a window without panes. When I exit, I see the errors:
can't find session: Editor
can't find session: Editor
can't find session: Editor
can't find session: Editor
can't find session: Editor
can't find session: Editor
can't find session: Editor
can't find session: Editor
can't find session: Editor
can't find session: Editor
can't find session: Editor
can't find pane: 3
can't find session: Editor
can't find session: Editor
You should use tmux split-window to achieve what you want. Keys sent by send-keys are interpreted as input in command line, not shortcut to operate tmux.
#!/bin/sh
# Note: the default window, pane index start from 0
# you may need to modify the following index if you changed it in .tmux.conf
# E.g.
# set -g base-index 1 # start window index at 1
# setw -g pane-base-index 1 # pane index starts at 1
tmux has-session -t development
if [ $? != 0 ]; then
tmux new-session -s Editor -n Desktop -d
# Set up main editor window
tmux select-window -t Editor:Desktop
# Create splits (must executed outside of the session)
tmux split-window -h -t Editor
tmux split-window -v -t Editor
tmux split-window -v -t Editor
tmux split-window -v -t Editor
# Load programs into panes
tmux select-pane -t 0
tmux send-keys -t Editor:Desktop 'ccb' Enter
tmux send-keys -t Editor:Desktop 'vim' Enter
tmux select-pane -t 1
tmux send-keys -t Editor:Desktop 'ccb' Enter
tmux send-keys -t Editor:Desktop 'working_set --watch .' Enter
tmux select-pane -t 2
tmux send-keys -t Editor:Desktop 'ccb' Enter
tmux send-keys -t Editor:Desktop 'clear' Enter
tmux select-pane -t 3
tmux send-keys -t Editor:Desktop 'ccb' Enter
tmux send-keys -t Editor:Desktop 'npm start' Enter
fi
tmux attach -t Editor

I cannot copy text to my clipboard when i scroll up in a terminal session. This seems to be because the text i'm highlightning is yellow in color rather than clear. I cannot scroll up in my tmux history and copy text to my clipboard with fn + cmd+c.
If I do not scroll the tmux session, copying to my clipboard works correctly when i press fn + cmd+c.
Here is an image that shows text that I cannot copy to my clipboard with fn + cmd+c.

I'd like to be able to create a new tmux window(tab) in a session called 'scratch' running a custom command (ie. 'ping www.google.com') without attaching to the session. I'd also like 'scratch' to be created if it doesn't exist.
How would the shell script be written?
Plagiarized and altered a bit from another of my answers, here's an example:
TMUX_SESSION_NAME='scratch'
tmux new-session -d -s $TMUX_SESSION_NAME >/dev/null
tmux new-window -t $TMUX_SESSION_NAME
tmux send-keys -t $TMUX_SESSION_NAME:1.0 'ping www.google.com' Enter
More info (my configuration):
Here's what I use to start my tmux sessions. The argument to the function would be the name of the session you want to create.
If this does not answer your question, please comment and edit your question to that it is more clear to me.
tmuxstart() {
tmux new-session -d -s $1 >/dev/null
tmux rename-window -t $1:0 'main'
tmux splitw -v -p 10 -t $1:0.0
tmux splitw -h -p 80 -t $1:0.1
#required; otherwise pane numbering is bs
tmux select-pane -t $1:0.0
tmux splitw -h -p 5 -t $1:0.0
tmux send-keys -t $1:0.2 'sudo htop' Enter
tmux send-keys -t $1:0.1 'tmux clock -t $1:0.1' Enter
tmux select-pane -t $1:0.0
tmux new-window -t $1
tmux rename-window -t $1:1 'second'
tmux splitw -v -p 10 -t $1:1.0
tmux splitw -h -p 80 -t $1:1.1
tmux select-pane -t $1:1.0
tmux splitw -h -p 5 -t $1:1.0
tmux clock -t $1:1.1
tmux new-window -t $1
tmux rename-window -t $1:2 'scratch'
tmux splitw -v -p 10 -t $1:2.0
tmux select-pane -t $1:2.0

I am new to Tmux. I know that you can write script to automate Tmux, in case your computer shuts down. I can write the following:
#!/bin/bash
tmux new-session -d -s MY_SESSION_NAME
tmux split-window -h
vim <path to file1>
This only opens up a 1 single vim editor page for file1, not in tmux, and not in any tmux split. Is it possible automate the file opening like this?
Here's an example of the automation I have on my tmux session.
Target a specific session/pane/window with <name>:<window>.<pane>, where window and panes are numbered, starting with 0.
Send-keys is the way to send a command to a particular tmux pane/window. the -d causes tmux to start in detached mode so you can keep sending more commands to it before actually attaching.
tmuxstart() {
tmux new-session -d -s sess >/dev/null
tmux rename-window -t sess:0 'main'
tmux splitw -v -p 10 -t sess:0.0
tmux splitw -h -p 80 -t sess:0.1
#required; otherwise pane numbering is bs
tmux select-pane -t sess:0.0
tmux splitw -h -p 5 -t sess:0.0
tmux send-keys -t sess:0.2 'sudo htop' Enter
tmux send-keys -t sess:0.1 'tmux clock -t sess:0.1' Enter
tmux select-pane -t sess:0.0
tmux new-window -t sess
tmux rename-window -t sess:1 'second'
tmux splitw -v -p 10 -t sess:1.0
tmux splitw -h -p 80 -t sess:1.1
tmux select-pane -t sess:1.0
tmux splitw -h -p 5 -t sess:1.0
tmux clock -t sess:1.1
tmux new-window -t sess
tmux rename-window -t sess:2 'scratch'
tmux splitw -v -p 10 -t sess:2.0
tmux select-pane -t sess:2.0
tmux splitw -h -p 5 -t sess:2.0
tmux clock -t sess:2.1
tmux select-window -t sess:0.0
tmux a -t sess
}
I am trying to write a template script for a development session using tmux. So i just need to run this script for opening a new dev environment. Each session will have multiple windows - say two. First window(Window1) can be created while creating the detached session as:
tmux new-session -s $TMUX_SESSION_NAME -d -n Window1
(Here TMUX_SESSION_NAME is the argument passed to the script to name the session).
However, how can I create another window under the same session?
Note that I can create it as below but that messes up when creating another session. Although tmux ls shows each session having 2 windows each, the second session contains all the env settings of the first session(Both are for completely different projects)
tmux new-window -n Window2
tmux attach -t $TMUX_SESSION_NAME
I suspect both/all sessions go under the same /tmp/tmux-SOME_ID/default socket and hence this problem.
Note that the first time i start a dev session all is good with both windows.
Any ideas?
TL;DR: probably with something like
tmux new-window -t $TMUX_SESSION_NAME
tmux rename-window -t $TMUX_SESSION_NAME:1 'second'

tmux splitw -h -p 80 -t $1:0.1

I am trying to write a script I can run/source so tmux set a specific layout and run commands. I have some results.
Here is what I've written so far:
selectp -t 1
splitw -v -p 15
splitw -h -p 50
selectp -t 1
send-keys 'cd ~/code/octoly' Enter
send-keys 'vim .' Enter
selectp -t 2
send-keys 'cd ~/code/octoly' Enter
send-keys 'drails c' Enter
new-window -d -n server -c ~/code/octoly
selectw -t 2
send-keys 'fd' Enter
splitw -h -p 50
send-keys 'cd ~/code/octoly' Enter
send-keys 'drails s' Enter
selectp -t 1
splitw -v -p 50
send-keys 'cd ~/code/octoly' Enter
send-keys 'be guard' Enter
What works more or less is the creation of the second window and the panes. Though the panes does not give me what I want. They are all created in the first window, none are created in the second.
Here is what I run to start tmux:
tmux new 'tmux move-window -t 99 \; source-file ~/.tmux/session_octoly'
Furthermore, where I'm really lost is that if I run each command by hand one by one, it gives me what I want.
What am I missing here?
First of all, you're using the -d flag in new-window that does not make the new window the current window:
If -d is given, the session does not make the new window the current window.
However I would probably spin up tmux in a different way, using tmux -f flag to use an ad-hoc config file that does what you want.
Please check the commands before running it in you're environment.
# File: ~/.tmux/octoly.conf
# Load default .tmux.conf
source-file ~/.tmux.conf
# setup octoly session
new-session -s octoly -n editor -d -c ~/code/octoly
send-keys 'vim .' Enter
split-window -v -p 15 -c ~/code/octoly
send-keys 'drails c' Enter
split-window -h -p 50 -c ~/code/octoly
# Select vim pane
select-pane -t 1
# create second window
new-window -n server -c ~/code/octoly
send-keys 'fd' Enter
split-window -h -p 50 -c ~/code/octoly
send-keys 'drails s' Enter
select-pane -t 1
split-window -v -p 50 -c ~/code/octoly
send-keys 'be guard' Enter
# Optional step, reselect window 1 (the one with vim)
select-window -t editor
Then you need to launch tmux using:
tmux -f ~/.tmux/octoly.conf attach
Another alternative would be to build a bash script sending the same commands.
Note: I've used the -c flag to specify the start directory instead of running every time a cd command. Given that every command is run in the same folder you can take them out in the split-window commands.
