ssh command takes the password only from stdin. It does not accept the password
from files. I tried the following method to pass the password to ssh through file. But, it does not worked.
mohanraj@ltsp63:~/Unix$ ssh mohanraj@server < pass Pseudo-terminal will not be allocated because stdin is not a terminal. mohanraj@server's password: mohanraj@ltsp63:~/Unix$
Here, “pass” is the file which contains the password.
