# Intro to using UNIX Screen

## Basics

	screen -list  # LIST current screen sessions

	screen -S myscreen1  # CREATE a new session named *myscreen1*

	screen -r myscreen1  # RESUME an existing detached screen session

	screen -D -r myscreen1  # RESUME an existing screen session, even if was left attaches (say by a dropped connection...)

	screen -R "my screen 1"  # RESUME or create a session named *my screen 1*

	screen -X -S <session no.> quit  # DESTROY session

	`C-a d`  # DETACH from current screen session


## Window Managing

	`C-a "`  # list menu of all windows (use number key then <kbd>Enter</kbd> to select one)

	`C-a 0`  # switch to window 0

	`C-a '` + `part or all of window name` + [Enter]  # switch to window by name

	`C-a c`  # create a new window

	`C-a A`  # give a name to current window

	`C-a k`  # kill current window (and detach session if this was the last one left)


## Shared Sessions

	screen -S myshared1  # create a session named myshared1

	# ...login from another terminal...

	screen -x -r myshared1  # connect to session myshared1


## Other shortcuts

	screen -S my1 -t one  # create a session named *ms1* with a windows named *one*

	screen -r my1 -p one  # resume session *my1* and go directly to window *one*


## Status Bar

	# You SHOULD use something like this to keep track of the window you are in.

	# Add to your `~/.screenrc` this black magic:

	hardstatus on
	hardstatus alwayslastline
	hardstatus string "%{.bW}%-w%{.rW}%n %t%{-}%+w %=%{..G} %H %{..Y} %m/%d %C%a "

	defhstatus "screen ^E (^Et) | $USER@^EH"
	hardstatus off
