find命令实用一例

目的：找到特定的文件并复制到另一个文件夹中。

我的数码相机里有如下文件：

我想把1月13日和1月14日的jpg图片复制到文件夹FX01里。可以用以下命令：

419@detch:~$ find /sdcard/ -newer /sdcard/p1010057.jpg -name *.jpg |xargs /bin/cp -t FX01/

以下命令会把全部比p1010057.jpg新的文件（包括jpg和mov）复制到FX01：

419@detch:~$ find /sdcard/ -newer /sdcard/p1010057.jpg -type f |xargs /bin/cp -t FX01/
