如何在 Windows CMD 树命令中附加尾部斜杠？

如何在 Windows CMD 树命令中附加尾部斜杠？

在 Windows CMD 中执行该tree命令将会给我一些如下输出：

C:\DIR1
│   foo.txt
│
└───dir2
        bar.txt

如何在目录后面附加斜杠以使其更清楚地表明它们不是文件？它应该适用于根目录和子目录，如下所示：

C:\DIR1\
│   foo.txt
│
└───dir2\
        bar.txt

概述

一个解决方案是使用Python脚本来包装命令并以此方式在每个目录的末尾tree添加尾随。\

以下脚本适用于 Python 3.x。如果您决定使用此脚本，您可能需要在命令行中安装 Python 以方便使用，并将.py文件与 Python 关联。

注意事项

  • 包装tree命令会使它稍微慢一些（由于脚本执行时间）。也就是说，这种差异可能很小，在大多数情况下可以忽略不计。

  • 我们已尽最大努力tree尽可能真实地重现 的输出（因此，tree除了添加 之外， 和 此脚本之间实际上应该没有区别\）。但是，理论上您可能会遇到一些未知的输出问题，具体取决于您的用例。

  • 您可能会遇到的一个问题是输出到文本文件。如果/A未指定，此脚本将崩溃。tree更优雅的是它只是写入“错误”的字符。

  • 可能出现的一个小问题是，当使用 ASCII（ ）输出模式时，从技术上讲，任何包含+---作为其名称一部分的项目（假设该项目不是目录）都有可能出现“误报” 。/A

  • 如果为变量指定完整路径（如下），则使用\\（而不仅仅是）。\root_dir

  • /F命令行中的实现/A是有意简化的。如果您想要更强大的功能，您应该查看参数解析（或者直接阅读tree /?）。

  • 此脚本是针对 Windows 7 和代码页编写的cp1252。cp437您可能需要根据您居住的地方等更改这些编码值。

脚本

笔记

tree运行时，它使用三个扩展管道符号 ( ───) 或三个连字符 ( ---) 作为目录名称的前缀。此脚本查找包含这些值的行，并\根据需要将其添加到这些行的末尾。

您可以使用初始show_files和值设置默认脚本选项。命令行ascii_tree选项可以分别是bonsai.py、bonsai.py /F或。bonsai.py /Abonsai.py /F /A

如上所述，root_dir它被硬编码到脚本中（即，它没有可以从命令行设置的选项）。

例如 bonsai.py：

# Wrapper for the Windows "tree" command, which adds a "\" to the end of
# directory names to more easily distinguish them from files.
