Enhance: Run as another user through sudo

[zokusai]

Hi,

I have the need to impersonate the execution of the command to achieve a password-less connection to the remote server with a user other than the current one.

To make it, I count on sudo to do the work and use in my sources the following piece of code as a quick workaround:

module Rsync

  class << self
    attr_accessor :sudo_as
  end

  class Command
    def self.run(*args)
      cmd = "rsync --itemize-changes #{args.join(" ")}"
      cmd.insert(0, "sudo -u #{Rsync.sudo_as} ") if Rsync.sudo_as
      output = run_command(cmd)
      Result.new(output, $?.exitstatus)
    end
  end
end

Don't know if it's a good way to do it, but I hope will be of any help for a future enhancement.

Regards,
