Is there a way we can avoid asking of password when we transfer file from one Unix server to another server using SCP command.
Or
Is is possible that the batch file in unix in which I am giving the SCP command takes the password and transfer the files automatically without me typing the password of the receiving server.
Pash
scp stands for Secure Copy, not for Secure Copy Paste. I'll change the subject of this thread.
You should read up on one of the many information sites on the web about ssh/scp. The authentication, especially the non-interactive is based on key authentication. No password needed in that case.
Therefore you'll have to generate a key pair and add the public key of the host that should get access to the authorized_keys file of the other one.
There is also many questions with solutions in this forum if you check for the strings "ssh passwordless" or "ssh without password".
They explain it more in detail.
General advice: Please use the search function of the forum first, thanks.
