xcopy

I just can't seem to find a way on the command line to say "copy all the files from directory A to directory B, but if the file already exists in directory B, don't overwrite it, no matter which file is newer, and don't prompt me." I have been through copy, move, xcopy & robocopy, and the closest I can get is that you can tell robocopy "copy A to B, but don't overwrite newer files with older files," but that doesn't work for me. I looked at xxcopy, but discarded it, as I don't want to have a third-party dependency on a Visual Studio post-build event that will require other SVN users to have

1、考虑下面的需求，把aaa目录下面的111.txt 拷贝到 bbb，如下： echo on xcopy .\aaa\111.txt .\bbb\ /y pause 2、注意这里表示路径要用右斜杠，因为左斜杠表示命名的选项，如test.exe /f cfg.xml 3、考虑下面的需求，把aaa目录下面的111.txt 拷贝到 bbb，并且重命名为222.txt，如下： echo on xcopy .\aaa\111.txt .\bbb\222.txt /y pause 执行过程，会提示 目标 .\bbb\222.txt 是文件名 还是目录名 (F = 文件，D = 目录)? 需要用户输入。 4、原因是，xcopy不知道222.txt是个文件还是目录？怎么解决这个问题，消除提示。 这就需要用户，显示地告诉xcopy，222.txt是目录还是文件。 如果希望222.txt是个目录，把111.txt拷贝到222.txt，修改为 xcopy .\aaa\111.txt .\bbb\222.txt\ /y 如果希望222.txt是个文件，也就是copy并且重命名，使用下面的方法，自动输入f 如下： echo f| xcopy .\aaa\111.txt .\bbb\222.txt /y 原理是通道的概念，前一个命令的输出作为后一个命令的输入。echo f 输出f，xcopy 提示输入

Each square contains either water (‘W’) or dry land (‘.’). Farmer John would like to figure out how many ponds have formed in his field. A pond is a connected set of squares with water in them, where a square is considered adjacent to all eight of its neighbors. Given a diagram of Farmer John’s field, determine how many ponds he has.
