How do I get PowerShell 4 cmdlets such as Test-NetConnection to work on Windows 7?

The situation. On a Windows 7 SP1 machine, I have updated with Windows6.1-KB2819745-x64-MultiPkg.msu. Furthermore, in PowerShell $PSVersionTable now reports ‘PSVersion 4.0’. At present, my conclusion is that many PowerShell 4 cmdlets such Test-NetConnection, will only work on Windows 8.1. However, I was wondering if there was a work-around whereby I could import PowerShell 4 modules on my Windows 7 machine. Knuckle-Dragger You cannot, they rely on underlying features of the newer OS (8.0 or 8.1) and cannot be ported back to W7. The alternative is to write your own functions / modules to

How to change tab width when converting to JSON in Powershell

由 守給你的承諾、 提交于 2019-12-03 02:40:59
I am creating a JSON in Powershell and I want to set a custom tab width when building it (instead of the default 4 white spaces I want to set only 2 white spaces). I am doing this because: the actual JSON (not the one presented in the below sample) is pretty big (100k+ rows) and if not archieved, it's size is pretty big; If I reduce the tab width the size reduction is notable. the actual JSON has a depth of 5+ nodes ! I cannot use -Compress since the JSON needs to be human readable Yes, I agree, if archived, it's size is dramatically reduced but I need it also unarchived. Sample code: $object

Equivalent of *nix fold in PowerShell

由 孤街醉人 提交于 2019-12-02 05:15:30
问题 Today I had a few hundred items (IDs from SQL query) and needed to paste them into another query to be readable by an analyst. I needed *nix fold command. I wanted to take the 300 lines and reformat them as multiple numbers per line seperated by a space. I would have used fold -w 100 -s . Similar tools on *nix include fmt and par . On Windows is there an easy way to do this in PowerShell? I expected one of the *-Format commandlets to do it, but I couldn't find it. I'm using PowerShell v4. See

问题 I want to emulate PowerShell 3.0 From PowerShell v3 or v4 you can emulate v2 with this command: %windir%\system32\WindowsPowerShell\v1.0\PowerShell.exe -version 2 $Host reveals: Version: 2.0 However, in PowerShell 4 %windir%\system32\WindowsPowerShell\v1.0\PowerShell.exe -version 3 $Host now reports: Version: 4.0 (I was hoping for 3:0) Question: Is there any way of emulating PowerShell 3.0 from 4.0? 回答1: No, it's not possible. V4 is backwards compatible with V3, so any script written

Function does not get binding when used in Module

I'm trying to put this function : function Test-Any { [CmdletBinding()] param($EvaluateCondition, [Parameter(ValueFromPipeline = $true)] $ObjectToTest) begin { $any = $false } process { if (-not $any -and (& $EvaluateCondition $ObjectToTest)) { $any = $true } } end { $any } } into a module. I just created a new module, the my-scripts.psm1 file, which contains just the above function and import it with Import-Module <absolute path> . The problem is that if I use the function from the module 1..4 | Test-Any { $_ -gt 3 } returns false, because $_ is not set to the value from the pipe. If I define
