Nohup problem

Hi

I need to execute about 1000 scp commands sequential , so I made "scp.sh" - like this

Code:
scp - rp ...
scp - rp ...
............
scp - rp ...

then I run
Code:
nohup sh scp.sh &

The problem is: nohup process stopped when I closed session, or when the session expired,... Something wrong SmilieSmilieSmilie

Can someone show me what the problem is SmilieSmilieSmilie and how to fix it. Thank you

I don't know for sure but it might be that scp allocates a terminal in case it needs to ask you for a password if the SSH-key authentication fails. Similar to SSH you might try to use:

Code:
scp -nqo 'BatchMode = yes' ....

I hope this helps.

I has already configed ssh-without-password for both servers.

Up to now, I still don't know why, maybe because one server is a Vios client - I guess. I solved it by crontab. Thanks for help SmilieSmilieSmilie

The problem is not the password-less authentification (BatchMode=yes) but the allocation of a pseudo-terminal by the scp-process. You can prevent that by using "-n". You might want to test that and see if it works.

Glad, you found a solution anyhow, though.

I hope this helps.
