  • Session: The largest unit managed by tmux. ?attach/detach? to the session. Even if you detach from the session, the session continues to run in the background.
  • Window: This is the same tab that exists in the session. You can have multiple windows in one session. You can create and switch windows within a session and switch the entire screen as you move tabs.
  • Pane: This is the screen unit existing in the window. You can have multiple panes in a window. If you divide the entire screen vertically by two, two panes are created.
