sftp/scp without password

[chuikingman]

Hi,
How can I use sftp/scp without password in linux. How can I use sftp/scp to write script and execute in cronjob ?? any example or sample script ??
Can I test sftp/scp within the same machine and the same user account ??
Like use one user account in one linux server to test whether the sftp/scp work or not ???any suggestion ???
Thank

You should really google all of your questions before posting them onto a forum. You would have found out that for no passwords on scp, you can use public key authentication.

sftp / scp do not run scripts, they are applications, not script interpreters. If you are asking can you call scp / sftp FROM a script, then yes, you can. If you don't know how, I suggest you search the linux documentation project (again, google for it.) for the bash scripting guide. It is a good start.

and yes, you can test any service from your own local computer to your local computer, just use 127.0.0.1 as the IP address, or `localhost` as the hostname.
