linux里如何查找目录中更改时间在指定日期以前的文件？

linux里查找目录中更改时间在2009年3月1日以前的文件，要怎么写？
就是指定日期以前的文件，用find命令好像只能查找n天或n分钟以前的文件。
多谢！

首先创建一个 test 文件，其时间刚好小于你需要的 2009年3月1日，然后：

find ./ -newer test -print

貌似就行了！

#2

find . -newerct "20090301"

#3

刚才看错了
find . ! -newerct "20090301"

#4

好像应该是    find . !  -newermt "20090301"

$ man find
......
       -newerXY reference
              Compares the timestamp of the current file with reference.   The
              reference  argument  is  normally the name of a file (and one of
              its timestamps is used for the comparison) but it may also be  a
              string  describing  an  absolute time.  X and Y are placeholders
              for other letters, and these letters select which time belonging
              to how reference is used for the comparison.

              a   The access time of the file reference
              B   The birth time of the file reference
              c   The inode status change time of reference
              m   The modification time of the file reference
              t   reference is interpreted directly as a time
