Shell Programming and Scripting

here's the sitch:

remote freeBSD device. I am ssh'd in as root and running cgsecurity's TESTDISK program. Testdisk will take DAYS to scan this multi-terabyte RAID. Can I quit my terminal or ssh connection, disconnect from the remote computer, come back to it later and NOT stop or interrupt the program running on the remote machine? And when I log back in, can I re-access the interface of the program?

If it were a brief app, I'd just experiment and see, but this is day 3 of a 7-day scan!

Thanks for the newbie help!

Danmero Thanks!

BUT

It looks like nohup has to be used when the app/process is started, and I'm in the middle of a recover, not starting it.

Is there a way to shut down my terminal session withOUT stopping the running process on the remote computer, and a way that I can return to see the results of that process (testdisk updates the terminal screen as it scans cylinders, etc)?

TIA

Thanks Pludi,

looks like screen also needs to be up adn going before the process is running, but it will help in the future!

I want to be clear in describing what I am doing, so here goes again:

I fired up a terminal session in Mac OS X

then ssh'd into a remote device:

Then got the freeNAS prompt:

I then installed Testdisk (MY FIRST UNIX INSTALL!!!) from the ports

Next I ran testdisk:

and got the testdisk interface:

Selected my options and got the scan going....

Now I am waiting while a lovely and simple text screen rolls through thousands of blocks an hour, stuck. Unable (I THINK) to disconnect from the remote device without interrupting testdisk.

Am I stuck this time?

Thanks!!
