Installing SSHPass
SSHPass is a tiny utility, which allows you to provide the ssh password without using the prompt. This will very helpful for scripting. SSHPass is not good to use in multi-user environment. If you use SSHPass on your development machine, it don't do anything evil.
apt-get install sshpass
Installing on OS X is tricky, since there is no official build for it. Before you get started, you need install xcode and command line tools.
Homebrew does not allow you to install sshpass
by default. But you can use the following unofficial brew package for that.
brew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb
./configure
sudo make install
