如何将树的结果传递或管道到 Powershell? [英] How to pass or pipe the results of tree to Powershell?

问题描述

如何填充通过 tree 找到的文件数组?

How can an array of files, as found through tree, be populated?

posh> 
posh>  tree ./  | Get-Item

    Directory: /home/nicholas/powershell

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
d----           2/21/2021  5:42 PM                regex
Get-Item: Cannot find path '/home/nicholas/powershell/regex/├── a.log' because it does not exist.
..
Get-Item: Cannot bind argument to parameter 'Path' because it is an empty string.
Get-Item: Cannot find path '/home/nicholas/powershell/regex/0 directories, 16 files' because it does not exist.

posh> 

这个例子没有子目录，但对于更复杂的目录，有子目录，希望捕获每个文件的完整路径和文件名.

This example has no sub-directories, but for more complex directories, with sub-directories, looking to capture, for each file, its full path and filename.

具体来说，然后搜索文件——但这个问题有点笼统.

Specifically, to then search the files -- but the question is of a somewhat general nature.

推荐答案

tree 是 Windows 和大多数 Unix 风格操作系统上的 CLI 程序，用于绘制文件结构的可视化表示.它不会生成目录数组.

tree is a CLI program found on windows and most Unix-style OSes for drawing a visual representation of a file structure. It does not generate an array of directories.

在 powershell 中，如果您想递归地获取目录结构的项目并将它们保存到变量(除非只返回一个项目，否则它将是一个数组)使用以下内容:

In powershell if you want to get the items of a directory structure recursively and save them to a variable (which would be an array except in the case where only a single item is returned) use the following:

$tree = Get-ChildItem -Recurse

这会将结果存储在变量 $tree 中.如果不想从当前位置开始，可以使用 -path 参数.例如

This will store the result in the variable $tree. You can use the -path parameter if you want to start not at the current location. E.g.

$tree = Get-ChildItem -Path "/home/dave" -Recurse
