How not to trim lines when printing environment variables in powershell?

To print environment in PowerShell I can do, according to this:

dir env:

So I did, and for example for Path and for other environment variables longer then my window I see:

 Path                      C:\Python39\Scripts\;C:\Python39\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;...

I do not want ..., I want to see the full length anything there is value of environment variable of all variables.

I tried to read: https://superuser.com/questions/1049531/how-to-fix-truncated-powershell-output-even-when-ive-specified-width-300 and tried to cd env: -Width 1000, or tried cd env: and then Get-ChildItem -Width 1000, it does not work, and searched google but with no success. The dir env: | Out-String -width 999 results in an endless amount of empty lines. What works is dir env: | cat, but then the names of variables disappear.

Is there any way I can view not-truncated values of all environment variables with variable names?

out-string behaves slightly differently on Windows PowerShell versus PowerShell Core - it looks like PowerShell Core uses -Width as a maximum width whereas Windows PowerShell pads each line to the specified width so you're seeing each environment variable separated by a lot of spaces.

PowerShell Core

PS 7.1.3> dir env: | out-string -width 9999

Name                           Value
----                           -----
ALLUSERSPROFILE                C:\ProgramData
APPDATA                        C:\Users\Mike\AppData\Roaming
CommonProgramFiles             C:\Program Files\Common Files
CommonProgramFiles(x86)        C:\Program Files (x86)\Common Files
CommonProgramW6432             C:\Program Files\Common Files

Windows PowerShell

PS 5.1> dir env: | out-string -width 9999

Name                           Value
----                           -----
ALLUSERSPROFILE                C:\ProgramData




APPDATA                        C:\Users\Mike\AppData\Roaming




CommonProgramFiles             C:\Program Files\Common Files




CommonProgramFiles(x86)        C:\Program Files (x86)\Common Files




CommonProgramW6432             C:\Program Files\Common Files

(padding not to scale!)

It's a bit ugly, but if you want to make Windows PowerShell output look the same you can do something like this:

PS> ((dir env: | format-table | out-string -width 9999) -split [System.Environment]::NewLine).Trim() -join [System.Environment]::NewLine

Basically, split the output into lines, trim them and then join them back together again.

Taking your question literally, if you just want to view the env variables with their untruncated values on the console, you can simply format the output as list:

Get-ChildItem env: | Format-List

This will display the information in the following fashion and insert visual line breaks if the value is longer than the available space:

Name  : PSModulePath
Value : C:\Users\{and so on}
