| + | observer@flexbuffhb DiFX-2.5.2 ~> screen -raAD | ||

| + | 18325.pts-4.flexbuffhb (14/05/19 13:53:38) (Detached) | ||
| + | Type "screen [-d] -r [pid.]tty.host" to resume one of them. | ||
| + | observer@flexbuffhb DiFX-2.5.2 ~> screen -raAD 18325 - Check if that is the screen you were using last!! | ||
| + | |||
| + | Commands to use inside a screen: | ||
