Powershell脚本打印出系统路径中的每个值

发布于 2024-11-30 14:20:47 字数 700 浏览 0 评论 0原文

我发现我可以在 PowerShell 中使用 $env:Path 来查看当前的系统路径。然而，一切都在一条线上运行。有没有办法将 $env:Path 的输出通过管道传输到另一个命令，该命令将单独打印每个路径值（即，为以分号分隔的所有内容打印在新行上）？

目前它打印如下内容：

C:\Some Test Directory\With\Some\Files\In\It;C:\Some Test Directory\With\Some\Files\In\It;C:\Some Test Directory\With\Some\Files\In\It;C:\Some Test Directory\With\Some\Files\In\It;C:\Some Test Directory\With\Some\Files\In\It;

我宁愿有这样的内容：

C:\Some Test Directory\With\Some\Files\In\It
C:\Some Test Directory\With\Some\Files\In\It
C:\Some Test Directory\With\Some\Files\In\It
C:\Some Test Directory\With\Some\Files\In\It
C:\Some Test Directory\With\Some\Files\In\It

I found that I can use $env:Path within PowerShell to see my current system path. However, everything runs together on one line. Is there a way to pipe the output of $env:Path to another command that will print each path value separately (i.e. printing on a new line for everything that is delimited by a semi-colon)?

Currently it prints something like this:

C:\Some Test Directory\With\Some\Files\In\It;C:\Some Test Directory\With\Some\Files\In\It;C:\Some Test Directory\With\Some\Files\In\It;C:\Some Test Directory\With\Some\Files\In\It;C:\Some Test Directory\With\Some\Files\In\It;

I'd rather have something like this:

C:\Some Test Directory\With\Some\Files\In\It
C:\Some Test Directory\With\Some\Files\In\It
C:\Some Test Directory\With\Some\Files\In\It
C:\Some Test Directory\With\Some\Files\In\It
C:\Some Test Directory\With\Some\Files\In\It

$env:Path.split(";")

PS C:\Users\user> $env:Path.split(";")
C:\Program Files (x86)\Haskell\bin
C:\Program Files (x86)\Haskell Platform\2011.2.0.1\lib\extralibs\bin
C:\Program Files (x86)\Haskell Platform\2011.2.0.1\bin
C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common
C:\Windows\system32
...

对我有用。

$env:Path.split(";")

PS C:\Users\user> $env:Path.split(";")
C:\Program Files (x86)\Haskell\bin
C:\Program Files (x86)\Haskell Platform\2011.2.0.1\lib\extralibs\bin
C:\Program Files (x86)\Haskell Platform\2011.2.0.1\bin
C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common
C:\Windows\system32
...

Works for me.

在 Unix 上，您可以简单地完成此操作。

echo $path | tr ";" "\n"

您可以使用以下任一方法在 Windows 上模拟此工作流程：

安装

gnu coreutils 并将 bin 目录添加到系统路径

或

将命令行工具的文件夹添加到系统路径。例如，“C:\Program Files (x86)\bin\”
下载 tr 作为移植自的 powertools 的一部分UNIX。将它们提取到其他地方。（例如，“C:\Program Files (x86)\bin\perl\”
将包含这些内容的名为 tr.bat 的 bat 文件添加到您的 bin 中。文件夹：

@回声关闭
perl“C:\Program Files (x86)\bin\perl\tr”%*

（路径应与提取 perl 工具的位置匹配）

结果

C:\>echo %path% | tr ";" "\n"
C:\Program Files (x86)\bin\
C:\Perl\site\bin
C:\Perl\bin
C:\WINDOWS\system32
C:\WINDOWS
C:\WINDOWS\System32\Wbem
C:\WINDOWS\System32\WindowsPowerShell\v1.0\
C:\Python27
...

On Unix you can do this with simply

echo $path | tr ";" "\n"

You can emulate this workflow on Windows with either of the following:

EITHER

Install gnu coreutils and add the bin directory to your system path

Add a folder for your command line tools to your system path. E.g, "C:\Program Files (x86)\bin\"
Download tr as part of the powertools ported from unix. Extract them somewhere else. (E.g, "C:\Program Files (x86)\bin\perl\"
Add a bat file called tr.bat with these contents to your bin folder:

@echo off
perl "C:\Program Files (x86)\bin\perl\tr" %*

(Path should match where you extracted the perl tools)

Result

C:\>echo %path% | tr ";" "\n"
C:\Program Files (x86)\bin\
C:\Perl\site\bin
C:\Perl\bin
C:\WINDOWS\system32
C:\WINDOWS
C:\WINDOWS\System32\Wbem
C:\WINDOWS\System32\WindowsPowerShell\v1.0\
C:\Python27
...
