Scripting TMUX

Starting multiple commands in multiple panes

Start a new tmux session with tmux before running the script!

# start a new tmux session and detach from it
tmux new-session -d -s session1

tmux rename-window 'my window'
tmux send-keys 'echo "pane 1"' C-m

tmux select-window -t session1:0
tmux split-window -h
tmux send-keys 'echo "pane 2"' C-m

tmux split-window -h
tmux send-keys 'echo "pane 3"' C-m

# we want to have notifications in the status bar, if there are changes in the windows
tmux setw -g monitor-activity on
tmux set -g visual-activity on

tmux select-layout even-horizontal

# select the first window to be in the foreground
tmux select-window -t session:1

# attach our terminal to the tmux session
tmux -2 attach-session -t cflogs

Configuring TMUX

You can configure tmux via the ~/.tmux.conf file. After making changes to the config file, you can update the configuration "on-the-fly" with

tmux source ~/.tmux.conf

Changing the default prefix

Use

set -g prefix C-a

to change the default prefix from CTRL + b to CTRL + a. Optionally you can "free" the default binding with

unbind C-b

Key Bindings

You can add / alter tmux's key bindings with the following command

bind | split-window -h

this binds the split window -h command to the | key.

Adding Mouse Support for Mac OS X

In order to have mouse support in Mac OS X, you can add the following lines to your config file:

set -g mode-mouse on
set -g mouse-resize-pane on
set -g mouse-select-pane on
set -g mouse-select-window on
