I.e., the Ctrl+ Z suspend key, and the jobs, fg, and bg shell commands. (Naturally, every command ends with the Enter key.)ġJob control is the arbitration between multiple process groups of a single session that uses the tty as its controlling terminal. tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. To tell tmux to send a newline key to the window. tmuxmay be detached from a screen and continue running in the When tmux is started, it creates a new sessionwith a single windowand displays it on screen. If you need to silently kick off a script in the background whenever you. tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. If the command doesn't return success, the exit sta- tus is also displayed. In order to start a basic session, just run the tmux command. After it finishes, any output to stdout is displayed in copy mode. Note that, on the send-keys command, you should actually type the letters From the tmux man page: run-shell shell-command (alias: run) Execute shell-command in the background without creating a win- dow. Tmux send-keys -t "$pane" C-z 'some -new command' Enter You might script it like this (attach last, because otherwise the script will just wait for you to detach before continuing): session=whatever If you want to clobber whatever is currently running in the pane, you can use respawn-pane -k to kill the existing command and replace it with a new one (e.g., respawn-pane -t sessionname:0.4 -k 'some -new command').īut, if you want to maintain whatever is currently running in the pane, then there may be no better option that simply “typing at it” with send-keys. It is up to that initial command’s process (usually a shell) to supply job control 1 for that terminal. Here are a couple of keybindings I use to open up popup windows. They always open in the middle (by default) when you open them, no matter where you leave them. Tmux does not supply a way to add extra processes to a pane once it has been started with its initial command. Tmux popups are actually floating windows that you can drag around the screen. Non-split windows have a single pane split windows have multiple panes. Each tmux pane is an interface for a single pty (pseudo tty).
