test
Ciaran
02:13:11
how do you run exit twice in a row? like I want exit to run on opus to kill my ssh session then I want it to run in my terminal windows on my computer to close it
Ciaran
02:13:37
but with one line instead of having to type exit twice
November
02:13:38
hey rich, if i start the test at 11, can i still be taking it till 1 or so even though other ppl will have left?
November

November

yeah, got it
Ciaran
02:16:53
I sent a question above november
Ciaran
02:17:57
you said when were terminating our connection to opus to use "exit" and not click the x on out termianl window
Ciaran
02:19:14
so what I have to do now is type exit in opus so I disconnect then type exit again in my terminal window so it goes away
Ciaran
02:19:20
is there a way to do that in one line'
Ciaran
02:19:22
