/>特别说明下，有的兄弟很细心，上面截图中说的是去掉_finished我的解答是针对去掉finished的，不过不影响大局，特请大家注意下。解答：[准备测试数据]mkdir /oldboy cd /oldboy touch stu_102999_1_finished.jpg touch stu_102999_2_finished.jpg touch

#使用mv命令进行更改文件，新的文件名字符串拼接是本题的重点。done#特别提示：通过本题，可以学习到for循环的使用，及mv、sed等命令的使用[执行脚本][root@oldboy oldboy]# sh oldboy_modi_file.sh [检查结果][root@oldboy oldboy]# lltotal 4-rw-r--r-- 1 root root 85 Oct  2 12:54
