Force SCP not to prompt for password

I'm writing script to test unix commands. one of them is the SCP command, where the certs are set up , so it did not ask for the password on normal scenario.

scp /tmp/test.txt  $userid@$hostname:$path

But assume scenario like certs were deleted or the user id is wrong then the script is not getting completed as scp asks for password

On the terminal

 scp /tmp/test.txt $userid@$hostname:$path
 Password:

So how can i force not to prompt for password and just fail in case it can not validate.

The scp command was stored in a variable line and is executed as below

`$line`
Solution

  • Typically:

    scp -o BatchMode=yes ..
