It occurs to me several times recently that when I open multiple terminals in golgi, and run jobs in background, only the one which I currently work on will keep alive, all those terminals that I've set up jobs but did not touch for while will become decay (lose connections). This morning I had two jobs in kaze/data/GSK.01, they became disconnected again. Even I set up the jobs to work in background using "&", it seems the jobs stopped at around 10:13am anyway.This does not seem to be a connection problem because I can get access to it if I open a new terminal. Does anyone know how to keep multiple terminals alive? Thanks.

this has nothing to do with keeping a terminal alive, but if you run your processes with "nohup" = no hang ups, they will run even if the terminal connection is lost.
ie: nohup ./NAMEofJOB > output.log &
this will run "NAMEofJOB" and will pipe anything that would be displayed in the terminal to "output.log", and it will run in the background |

Here's an additional trick:
./NAMEofJOB >& output.log &
The ">&" will redirect standard output and standard error to the file output.log. So if the program (or programs that it calls) produce error messages on standard error, they will go into output.log too. (This works for most shells, including bash and tcsh). |
