我试图找到在最后 x 分钟修改过的文件,例如在最后一个小时。网上的许多论坛和教程建议使用 find 命令和 -mmin 选项,如下所示:
find . -mmin -60 |xargs ls -l
然而,这个命令并没有像预期的那样对我起作用。从下面的清单中可以看到,它还显示了1小时前修改过的文件:

事实上它只是列出了工作目录里的所有文件。我们可以以这些文件中的一个为例,检查它的修改时间是否真的如 ls 命令所显示的那样:
stat 1446070435.V902I67a5567M283852.harvester

正如我们所看到的,这个文件肯定是最后一次修改 早些时候比1小时前!我也尝试了 find -mmin 60
或 find -mmin +60
,但它也没有工作。
为什么会发生这种情况,以及如何正确使用 find 命令?
