Your are on the sp_ctrl command prompt but need to run an OS command from sp_ctrl and need to get back to sp_ctrl once the OS command executes.
Wish to execute OS commands from sp_ctrl.
It is not possible to run OS command from sp_ctrl prompt. One needs to exit sp_ctrl, issue the OS command and then relaunch sp_ctrl. Another way to do this is to keep another session open for the OS and switch between two windows for running OS and Shareplex commands respectively.
