如何将树的结果传递或管道传递到Powershell?

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.

此示例没有子目录，但是对于具有子目录的更复杂的目录，它们希望为每个文件捕获其完整路径和文件名.

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 是一个CLI程序，可在Windows和大多数Unix风格的OS上找到，用于绘制文件结构的直观表示.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，如果要递归获取目录结构的项目并将其保存到变量(除非仅返回单个项目的情况下，否则为数组)，请使用以下命令:

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.如果您不想从当前位置开始，则可以使用 -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
