不能递归复制一个隐藏目录 - UNIX

Question

我目前正试图递归使用此命令

cp -r ../openshiftapp/.openshift . 

它不工作复制一个隐藏目录..什么可以是错误的？

Answer 1

在OS X上，你应该使用-R而非-r。手册页（在Snow Leopard 10.6.8上）说：

历史版本的cp实用程序有一个-r选项。该实现支持该选项;然而，它的使用是强烈的不鼓励，因为它不正确地复制特殊文件，符号链接或fifo的。

cp命令的递归选项将用于目录而不是文件。该文件指出：

-R, -r, --recursive 
      copy directories recursively 

的OSX docs有更多的信息，但不建议在选项可以与文件一起使用。相反，它仍然提到了它们用于复制目录内容：

-R If source_file designates a directory, cp copies the directory and the entire subtree connected 
      at that point. If the source_file ends in a /, the contents of the directory are copied rather 
      than the directory itself. This option also causes symbolic links to be copied, rather than 
      indirected through, and for cp to create special files rather than copying them as normal files. 
      Created directories have the same mode as the corresponding source directory, unmodified by the 
      process' umask. 

      In -R mode, cp will continue copying even if errors are detected. 

      Note that cp copies hard-linked files as separate files. If you need to preserve hard links, consider using tar(1), cpio(1), or pax(1) instead.
