tmux cheatsheet

Config File

The default <prefix> key is Ctrl-b. To get more screen-like behavior, change the <prefix> to Ctrl-a in ~/.tmux-conf like this:

unbind C-b
set -g prefix C-a

In Screen, to send Ctrl-a to an application, you must hit Ctrl-a a. Enable this for tmux using the following ~/.tmux-conf entry:

bind-key a  send-prefix

Vi style navigation between panes (splits)

bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

start new session: tmux
start new named session: tmux new -s myname
attach to running session tmux a (or at, or attach)
attach to running named session: tmux a -t myname
list sessions: tmux ls
kill session: tmux kill-session -t myname
Kill all tmux sessions: tmux ls | grep : | cut -d. -f1 | awk '{print substr($1, 0, length($1)-1)}' | xargs kill

Note <prefix> is Ctrl-b by default unless configured otherwise, see above.
