stream(command, options={})

Streams the result of the command from all servers that are the target of the current task. All these streams will be joined into a single one, so you can, say, watch 10 log files as though they were one. Do note that this is quite expensive from a bandwidth perspective, so use it with care.

The command is invoked via invoke_command.

Usage:

      desc "Run a tail on multiple log files at the same time"
      task :tail_fcgi, :roles => :app do
        stream "tail -f #{shared_path}/log/fastcgi.crash.log"
      end
