Make SCP run in background?

Moonman · 11-28-2007, 07:06 PM

Does anyone know how to kick off an SCP file copy and make it run in the background so it will continue to run after disconnecting the session?

I have tried various combinations of using nohup and the & but the password prompt is what is preventing me from getting it to work.

ie. nohup scp filename user@host: &

The process gets hung up in the background because it is waiting for a password to be entered.

Thanks,

Hello,

You could setup SSH keys for this, then you will be able to ssh or scp without a password from one server to another. Make sure you can run it interactively before running though nohup to test it works ok. Also as an alternative to nohup you could schedule the job using cron or use screen to run an interative session.

Screen is probably your best bet.

The other main cool feature of screen is its ability to decouple the terminal emulator from the running programs. This means that you can use screen to keep programs running after you accidentally close the terminal emulator, or even after you log out, and later resume right where you were. It means that the idea of a "session" in which you are running a number of console programs is a free-floating entity that you can bind to any terminal anywhere, or no terminal at all if you want.

I will agree with farslayer you should really look into screen, I use it a work to kick of some scripts and then check on the progress from home sometimes
