Is there a command you can add that will tell someone its processing in a terminal so if its busy some people wont think there is an error?? Hope this makes since.
If you run a command in a shell and the command takes a long time and does not produce any output at all, you can't run anything else in that particular shell until the original job finishes. You can push the job to the background if you want. Sorry, not sure what you're asking about? Can you give an actual example?
