![]() ![]() ![]() When TMUX pops up for the first time, it will execute some arbitrary commands, and never do them again unless the file ".automatic_startup_occurred" is removed. This is exactly what I was looking for my system to do - After booting, TTY1 will pop up with TMUX, and the other TTYs will be left alone. It's followed by: if ] & ] thenĪgain for newbies, this says "If $TMUX is non-zero in length, and the file ".automatic_start_occurred" does not exist (the "!" in the if statement), make the file "/root/.automatic_start_occurred" and then execute "hello_world" in /usr/bin. 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. Now that it's set to auto-login, I added the following to /root/.bashrc: if ] & ] thenįor newbies reading this, this says "If my terminal is terminal 1, and the $TMUX variable is zero-length, run tmux". tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. An output block consists of a begin line followed by the output (which may be empty). Each command will produce one block of output on standard output. tmux does not supply a way to add extra processes to a pane once it has been started with its initial command. In control mode, a client sends tmux commands or command sequences terminated by newlines on standard input. Non-split windows have a single pane split windows have multiple panes. I was able to do that by editing /etc/init/tty.conf: exec /bin/mingetty -autologin root $TTY 3 Answers Sorted by: 113 Each tmux pane is an interface for a single pty (pseudo tty). In my particular case, I'm running CentOS 6, and have it set to auto-login with root since it's just a test image. 4 Answers Sorted by: 4 In my case, I have a user account just for the purpose of running one single script, so I provide a default tmux configuration in that user's home directory by creating a file /.nf My /.nf file looks (roughly) like this: new-session -d -s MYSESSIONNAME set -g status off new-window /my-startup-script. The $TMUX variable will be populated with something like: "/tmp/tmux-0/default,27389,0" if TMUX is running. bashrc executes both when a new tty is opened, and when TMUX is opened in a terminal.įor future readers: The $TMUX variable is typically referenced to see if TMUX is running at all, but you could also use "pidof tmux". Thanks to JohnKiller's suggestion, I realized that. ![]()
