推荐答案

好的，首先，当你发布一个问题，总是建议你发布你迄今为止尝试过的代码，这样我们就可以帮助你调整和学习。那就说了，你尝试了什么？


我不熟悉xcopy，但你总是可以查看名为文件::复制，可以复制文件。如果它是您要移动的目录而不仅仅是文件，那么您将需要阅读 File :: Copy :: Recursive 。


对于你想做的任何事情，只需搜索CPAN并查看什么是可用的。


至于你的调用命令行问题，我不确定你在问什么。如果它想要从Perl脚本运行系统级命令那么简单，那么只需将命令及其选项包含在后面的标记中：

Ok, first, when you post a question, it is always recommended that you post the code that you have tried thus far so we can help you tweak it and learn. That said, what have you tried?

I am not versed in xcopy, but you could always check out the module called File::Copy, which will enable you to copy files. If it is directories that you are looking to move and not just files, then you will want to read up on File::Copy::Recursive.

For anything you want to do, just search CPAN and see what is available.

As for your "invoking the command line" question, I am not exactly sure what you are asking. If it is as simple as wanting to run a system level command from a Perl script, then just enclose the command and its options in back ticks:

如果在Windows上：

if on windows:

c:\>xcopy /?

我试过的代码，并使用了你曾建议的file :: copy模块

Hi,
following piece of code i tried,and used file::copy module which u had suggested
