按名称查找超过 60 天的目录

【问题标题】：Find directories that are older than 60 days by name按名称查找超过 60 天的目录

【问题描述】：

我有一个包含一些文件和子目录的目录。在该目录中，我需要按名称模式“.cm-2015.10.10”查找超过 30 天的文件。此命令为我找到所需的目录：

find comdit/ -type d -name .cm-[0-9][0-9][0-9][0-9].[0-9][0-9].[0-9][0-9] -print

但是如何指定我只需要 60 天以前的文件夹？添加 -ctime +60 对我没有任何帮助。我做错了什么？

你要找的是-mtime：

find comdit/ -type d -mtime +30 -name .cm-[0-9][0-9][0-9][0-9].[0-9][0-9].[0-9][0-9] -print

这里是文档：

   -atime n
          File was last accessed n*24 hours ago.  When  find  figures  out
          how  many  24-hour  periods  ago the file was last accessed, any
          fractional part is ignored, so to match -atime +1, a file has to
          have been accessed at least two days ago.

   -ctime n
          File's status was last changed n*24 hours ago.  See the comments
          for -atime to understand how rounding affects the interpretation
          of file status change times.

   -mtime n
          File's data was last modified n*24 hours ago.  See the  comments
          for -atime to understand how rounding affects the interpretation
          of file modification times.
