UNIX，如何维护目录结构? [英] UNIX, how to maintain directory structure?

问题描述

我想从非空目录树 bar1 创建一个空目录结构 bar2.bar1 和 bar2 都在同一层级.如何以有效的方式使用 mkdir 以便自动创建中间目录?

I want to create an empty directory structure bar2 from a nonempty directory tree bar1. Both bar1 and bar2 are at the same hierarchical level. How can I use mkdir in an efficient manner so that intermediate directories are automatically created?

1. 从 bar1 创建目录列表，并在必要时对其进行查找和排序.
2. 使用 awk，从列表中删除所有分支，这样我就可以只在叶子上运行 `mkdir.
3. 使用列表运行 mkdir 以复制 bar1 的目录结构

1. To create a directory list from bar1 with find and order it if necessary.
2. Using awk, remove all branches from the list so that I can run `mkdir only on the leaves.
3. Run mkdir with the list to replicate the directory structure of bar1

推荐答案

问题的难点(如何仅列出叶目录)是 之前问过SO.您可以在那里使用 find/awk 组合并在每个结果上运行 mkdir -p :

The hard part of your question (how to list only leaf directories) has been asked before on SO. You can use the find/awk combo there and run mkdir -p on each result:

[bar1] $ find . -type d | sort | awk '$0 !~ last {print last} {last=$0} END {print last}' | xargs -Ix mkdir -p ../bar2/x
