Need to query hundreds of hosts with an ssh command ?
Of course you'll have setup keys on all your remote HOSTs. But in the case a key is not present this command will skip that node, proceeding on to the next.
Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine. Also prevents unwanted stty messages being sent to console

If set to yes, passphrase/password querying will be disabled. This option is useful in scripts and other batch jobs where no user is present
There are 4 alternatives - vote for the best!
