In psuedo-script: #!/bin/bash ./program << (PRESS CONTROL-Z) The program is running so if there were additional commands in the script they will not be reached unless say control-z terminates the program. Is this possible? From what I've found I thought it mig...
I sweated over the question above. The answer I'm going to supply took me a while to piece together, but it still seems hopelessly primitive and hacky compared to what one could do were completion to be redesigned to be less staticky.
