![]() It might look like your work has vanished, but actually, you've created what tmux calls a window (which can be, admittedly, confusing because you probably also call the terminal you launched a window). Now press Ctrl+B followed by C on your keyboard. First, do something in your current terminal to help you tell it apart from another empty terminal: $ echo hello There's more going on, though, and you can see it with this little experiment. When you do this, the obvious result is that tmux launches a new shell in the same window with a status bar along the bottom. To start tmux, open a terminal and type: $ tmux On Mac, use Homebrew.įor example, on RHEL or Fedora: $ sudo dnf install tmux Start tmux On Linux and BSD, you can install tmux from your software repository or ports tree. You can build an array of terminals with just a few keyboard shortcuts or a rudimentary tmuxinator script. However, tmux adds in the ability to split a window into panes, with each pane containing a separate terminal, and each terminal can be logged into a separate host. ![]() After all, modern terminal applications, such as GNOME Terminal and Konsole, have tabs built-in by default, and even some very old terminals, such as rxvt, have the ability to add a tabbed interface. The result is a tabbed interface (without the physical tabs), so you can flip from one open terminal to another without having to use the mouse the way you have to when switching from one tab in Firefox to another. Tmux is an open source application that adds layers (or "windows," in tmux terminology) to your terminal window so that you can open more than one terminal in a single desktop window. For that, you need tmux, a single terminal that puts you in control of multiple command prompts. But sometimes you need to run commands manually. Ansible, for instance, ensures all systems are in the same state, and sometimes a simple cron job will do. There are many ways to automate tasks across systems. Focus would be in window 2 (foo/bar), top pane (foo).īyobu makes setting up and starting tmux automatically very simple.Whether you're starting up an elaborate Raspberry Pi homelab or you're managing a building full of workstations, sometimes you need to do the same task on multiple hosts. This would open 2 windows, the second of which would be named foo/bar and would be split vertically in half (50%) with foo running above bar. nf as below: # initialize sessionsĪnd then you can format the sessions as you require: #session1 ![]() You can configure different sessions from your. You should use sudo -i to emulate a full login, which also loads roots ~/.profile, and this is where byobu will install itself when you run The -s option only starts a shell, not a login shell. When the root user logs in via the console, SSH, or with sudo -i, Byobu will attach to an existing tmux session or create a new one if one is not already running. In a terminal, run following commands: sudo apt-get install byobu You can use Byobu as an interface to tmux to address this need, it makes it simple to do what you are asking. It can be easy to enable and disable automatic tmux sessions on login by using Byobu application. When you next start your tmux session, enter the command Ctrl- b + Ctrl- r to restore your tmux session.Īs mentioned previously, in addition to setting up the pane layout of the tmux session, this plugin can also set up persistent working directories as well as have your running applications restart with each session.Save your tmux session by entering the command Ctrl- b + Ctrl- s.Reload the tmux environment with the command: tmux source-file ~/dotfiles/tmux/nf.nf file and add the line set -g 'tmux-plugins/tmux-resurrect'. In the terminal ( Ctrl+ Alt+ t), navigate to your tmux plugin directory(in myĬlone the repository with the command: git clone.Monitors) programs running within a pane!
