In this case there is no '\@' so \n" 14 ."we should expect make to display the command AND display the \n" 15 ."echoed message. Secondly, make is run with the clean target, \n" 16 ."but since there is a '\@' at the beginning of the command, we\n" 17 ."expect no output; just the deletion of a file which we check \n" 18 ."for. Third, we give the clean target again except this time\n" 19 ."we give make the -n option. We now expect the command to be \n" 20 ."displayed but not to be executed. In this case we need only \n" 21 ."to check the output since an error message would be displayed\n" 22 ."if it actually tried to run the delete command again and the \n" 23 ."file didn't exist.
