awk输出特殊字符

awk '{print "insert into algorithm(algorithm_name, test_case_name) values('\''NR'\'',""'\''"$1"'\''"")"}' fft

的输出如下：

insert into algorithm(algorithm_name, test_case_name) values('NR','test_case_name_1')

awk '{print "insert into algorithm(algorithm_name, test_case_name) values(""'\''"NR"'\''"",""'\''"$1"'\''"")"}' fft

的输出如下：

insert into algorithm(algorithm_name, test_case_name) values('1','test_case_name_2')
