To display a list of Tmux commands, type: Ctrl-b ? Once you get the hang of the prefix combination, you can pretty much bootstrap yourself into learning Tmux with just one command. The prefix combination is really important. When inside a Tmux session, the prefix is nearly always pressed before the shortcut key to trigger a command. Press the Ctrl key AND the letter b at the same time. Once Tmux is installed, start a new Tmux session from the command line: $ tmuxĬtrl-b is the prefix combination.

If you have permission on the servers you use, you can update them with a similar configuration, in /etc/ssh/sshd_config: ClientAliveInterval 300 If you have a slow or unreliable internet connection, consider changing ServerAliveInterval to a lower number to send more frequent messages. You should tweak these settings to suit your needs: for instance by restricting the host to specific domains you can have different settings per domain. If the local machine sends 3 unanswered messages, it will disconnect the session. This configuration instructs your local machine for all user ssh sessions to send a server alive message every 300 seconds to keep the ssh session alive. Make ssh “keep alive” for all connections by adding this to ~/.ssh/config: host * Tmux is highly configurable but the first change I’d recommend is to ssh, not Tmux. Setupįirst you’ll need to install Tmux via your package manager or download it. If you do most of your programming at the command line, you’ll find using a terminal multiplexer invaluable.

You can manage several terminals under a session, split terminal screens, detach and re-attach sessions and much more. Tmux is a terminal multiplexer: it’s like a power-up for terminal programming.
