linux mv 命令怪异之处

Question

谁能告诉我为什么当我输入：

mv -f ./tmp/members ./

我得到：

mv: cannot move `./tmp/members' to a subdirectory of itself, `./members'

此外，移动该目录的正确方法是什么？

此外，./members 下已经有一个目录...我想完全覆盖这个目录，而不仅仅是向其中添加新内容。

Directory Structure:
./
./members
./members/srno
./members/srno/expired
./members/1
./members/1/active
./members/members
./members/members/srno
./members/members/srno/expired
./members/members/1
./members/members/1/active
./members/members/57364
./members/members/57364/expired
./members/members/11939
./members/members/11939/expired
./members/members/123
./members/members/123/expired
./members/members/73331
./members/members/73331/expired
./members/members/88144
./members/members/88144/expired
./members/members/25051
./members/members/25051/expired
./members/57364
./members/57364/expired
./members/11939
./members/11939/expired
./members/123
./members/123/expired
./members/73331
./members/73331/expired

Answer 1

请尝试以下操作：

cp -rf ./tmp/members/* ./

随后，./tmp/members如果您不想保留副本，请删除。 mv不会“覆盖”。

使用相对路径是一个坏习惯，你很快就会后悔。我建议在合理的情况下使用完整路径。

Answer 2

这应该有效：

mv -f ./tmp/members .

Answer 3

另一个答案（尽管你已经接受了另一个）：

mv ./members ./.trash-members ; mv ./tmp/members ./ ; rm -rf ./.trash-members &

这样，旧目录就会在后台被删除，新目录就会在很短的时间内放到位（只要您在同一个文件系统上，这两个移动就会非常快）

还请注意，该解决方案没有按应有的方式使用安全临时文件。
