tmux

tmux at a glance

tmux is a widely used terminal multiplexer, letting admins run and persist multiple terminal sessions in one window and keep them alive across disconnects — a staple for remote server work. tmux ships releases in an unhurried cadence plus fixes.

For admins tmux is low-risk and usually comes from the distribution. The update driver is features and compatibility rather than security, though keeping it current picks up any parsing fixes. Its real value is operational: persistent sessions mean a dropped SSH connection doesn't kill your long-running task, and you can reattach later — invaluable for maintenance work. Configuration is per-user; back up your config if you invest in it. There's little to maintain beyond a current version. A note: tmux sessions persist as the user, so on shared systems be mindful of leaving sensitive sessions attached. Related tools include screen and zellij.
