Tmux notes

Personnal notes while experimenting on tmux, not intended for sharing for the moment
If you ever come across this, feel free to comment if you have something useful to share with me :-)

Resources

Browsable man page for tmux, convenient

Default shortcuts

• n Change to the next window.
• o Select the next pane in the current window.

Misc

• <prefix> d send current session to the background

Targeting a pane

> tmux split-window -h -t 2:1.1 # session 2, window 1, pane2

Doesn't seem to work when invoked from tmux session with <prefix>:split-pane (makes kind of sense that commands invoked this way concern the current session)

Naming everything

Default session names and windows names start from 1 and increment

> tmux new-session -d -s my_session # -d for detached, -s to name
> tmux ls  # list existing sessions (see how they are named!)

• tmux rename-session -t my_session my_awesome_session rename targeted session
• tmux rename-window -t my_awesome_session:1 first_window
• looks like I can't rename a pane (tried select-pane -T <title> but didn't work)

Creating new windows, panes

tmux new-window -t my_awesome_session:2 -n plouf seems you have to provide a number (for ordering the windows) non taken by another window, and optionnaly a name

Sending commands to windows

not specified but you can target a session with the -t option

tmux send-keys "ls -lh" C-m
