      Short Answer \/ Higher-Order Questions<\/strong><\/p>\n\n\n\n

      20. Short Answer<\/strong><\/p>\n\n\n\n

      A student writes the following command and gets an error:<\/p>\n\n\n\n

      var=hello there<\/p>\n\n\n\n

      Explain why this happens and write the corrected command.<\/p>\n\n\n\n

      Sample Answer:<\/strong>
      The shell treats the space as a separator. It reads var=hello as one part and there as another command or statement. Since there is not a valid command, an error occurs.<\/p>\n\n\n\n

      Correct command:<\/p>\n\n\n\n

      var=”hello there”<\/p>\n\n\n\n

      The double quotes keep hello there together as one value.<\/p>\n\n\n\n
