内容四：stat 命令的使用案例
4.1 案例一：显示某个文件的时间
[mingyuzhu@liux ~]$ stat -c %y test.txt
2025-03-31 17:26:11.399060089 +0800或者：
[mingyuzhu@liux ~]$ stat --format=%y test.txt
2025-03-31 17:26:11.399060089 +0800（补充：这里以显示 test.txt 文件的时间为例）
4.2 案例二：显示某个文件的时间 （不换行）
[mingyuzhu@liux ~]$ stat --printf=%y test.txt
2025-03-31 17:26:11.399060089 +0800[mingyuzhu@liux ~]$ （补充：这里以显示 test.txt 文件的时间为例）
