tmux allows you to create multiple tabs and panes within a single terminal window. It can also keep programs running after you disconnect (e.g. when you ssh into an AWS instance)
Session- Saved collection of windows and panes and programs you left running inside
Attaching- Enter a running session
Detaching- Exit a running session (without killing it)
Window- Similar to a tab in your browser. Only one window is visible at a time.
Pane- Belongs to a window. You can have many of these visible at once.
Here is a list of the most common commands that will get you 90% of the way there.
Typically these are run outside, but you can also run them inside an existing session
Start New Session
tmux new -s myname
Attach To Existing Session
tmux a -t myname #by name tmux a 4 #by number (in this case 4)
tmux kill-session -t myname
