cp

我有一个包含符号链接文件夹的文件夹。

当我使用cp -r复制此目录时，文件夹会复制，但由于-r遵循符号链接，因此版本2将被复制两次。

当我使用cp -R复制此目录时，该文件夹第一次复制并保留符号链接。 但是，在第二个副本上，它无法覆盖该文件夹，说明：

我也试过cp -a == cp -pPR以及-f版本（ cp -fR和cp -fa ）

我认为通过遵循符号链接来查看Current Folder是否是文件夹，然后无法用符号链接覆盖符号链接（它认为它是一个文件夹）。

使用符号链接文件夹一致地复制和覆盖文件夹的正确命令是什么？

I have a folder that contains symlinked folders.

When I copy this directory with cp -r, the folder copies, but since -r follows symlinks, version 2 is copied twice.

When I copy this directory with cp -R, the folder copies fine the first time and preserves the symlinks. However, on the second copy, it is unable to overwrite the folder, stating:

I also tried cp -a == cp -pPR as well as the -f versions (cp -fR and cp -fa)

I think it's tests to see if Current Folder is a folder by following symlinks and then fails to overwrite the symlink (which it thinks it's a folder) with a symlink.

What's the right command to consistently copy and overwrite a folder with symlinked folders?

在OSX上，使用ditto

它具有与osx复制/粘贴相同的行为。

PS一个你可能需要注意的问题：

将文件夹foo /移动到bar /（即bar / foo / file1，bar / foo / file2）

将文件夹foo /的内容移动到bar（即bar / file1，bar / file2）

On OSX, use ditto

It has the same behavior as osx copy/paste.

P.S. One gotcha that you might want to watch out for:

will move the folder foo/ into bar/ (ie bar/foo/file1, bar/foo/file2)

will move the contents of folder foo/ into bar (ie bar/file1, bar/file2)
