    How do I automate this in bash?

    I'm trying to find a way to do this in a bash script instead of manually typing 'yes' when ssh asks:
    Code:
    $ ssh `hostname` # enter "yes"
    $ exit
    $ ssh localhost # enter "yes"
    $ exit
    I tried this, but it didn't work:
    Code:
    echo "yes\nexit\n" > $(ssh `hostname`)
    It still waits here for me to type something:
    Code:
    The authenticity of host 'myhost (10.1.2.3)' can't be established.
    RSA key fingerprint is 32:5d:aa:67:1f:76:bb:68:dd:d2:79:39:cc:21:ee:e0.
    Are you sure you want to continue connecting (yes/no)?
    Any ideas?

    No programming language is perfect. There is not even a single best language; there are only languages well suited or perhaps poorly suited for particular purposes.

    Why not just add -o StrictHostKeyChecking=no to the command line?

    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}

    I don't know much about ssh options, but I don't think that will add the host to the known_hosts file which is what I need to do.
    I need to make it so that when some other programs do "ssh `hostname`" they won't get prompted to enter yes/no.
