# Run the system command +cmd+.  If multiple arguments are given the command
  # is run directly (without the shell, same semantics as Kernel::exec and
  # Kernel::system).
  #
  # It is recommended you use the multiple argument form over interpolating
  # user input for both usability and security reasons.  With the multiple
  # argument form you can easily process files with spaces or other shell
  # reserved characters in them.  With the multiple argument form your rake
  # tasks are not vulnerable to users providing an argument like
  # <code>; rm # -rf /</code>.
  #
  # If a block is given, upon command completion the block is called with an
  # OK flag (true on a zero exit status) and a Process::Status object.
  # Without a block a RuntimeError is raised when the command exits non-zero.
  #
  # Examples:
  #
  #   sh 'ls -ltr'
  #
  #   sh 'ls', 'file with spaces'
  #
  #   # check exit status after command runs
  #   sh %{grep pattern file} do |ok, res|
  #     if !ok
  #       puts "pattern not found (status = #{res.exitstatus})"
  #     end
