Powershell script to print out each value in the system path

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 valu开发者_如何学编程e 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
...

Works for me.


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

OR

  1. Add a folder for your command line tools to your system path. E.g, "C:\Program Files (x86)\bin\"

  2. Download tr as part of the powertools ported from unix. Extract them somewhere else. (E.g, "C:\Program Files (x86)\bin\perl\"

  3. 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
