What is Tmux?
Tmux is a terminal multiplexer that lets you:
Run multiple terminal sessions in one window
Detach and reattach to sessions
Split your terminal into panes
Keep processes running after disconnecting
Basic Concepts
Sessions: Independent workspaces
Windows: Tabs within a session
Panes: Splits within a window
