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

+ | There are several suitable screens on: | ||

+ | 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: | ||
+ | ctrl+a c - creates | ||
