Initiate a screen session and disconnect immediately
[root@nodea ~]# screen -S 'jhtest' -d -m
[root@nodea ~]# screen -list
There is a screen on:
2653.jhtest (Detached)Parse a command to a running screen session
- Initiate and disconnect from your named screen session
screen -r "jhtest" -X stuff $'cd /benchmark\n'-r= reconnect screen session"jhtest"= name of the screen session-X= send commands to a running screen sessionstuff= stuff command lets you send keystrokes$=$before the command is to make the shell parse the\ninside the quotes and the newline is required to execute the command (like when you press enter)'cd /tmp\n'= the command to run followed by\nkeystroke
Injecting a command into an existing, remote screen session
Much the same as above:
ssh 172.28.130.1 screen -dmS test
ssh 172.28.130.1 screen -S test -p 0 -X stuff "/pool/LEOPARD150723M_2.16/Yafuflash\ -kcs\ /pool/LEOPARD150723M_2.16/LEOPARD150723M_2.16.ima\ -ignore-module-location"`echo -ne '\015'`-dmS= create a new detached screen session (dm) and name it (S"test").
-S test= name of the screen session-p 0= select screen 0 of screen session-X= send commands to a running screen sessionstuff= stuff command lets you send keystrokes`echo -ne '\015'`= send a carriage return after the main command, similar to$and\nin previous example.
NB: It seems an escape character (\) needs to be entered before a <space>.
