Question:
In PowerShell 2.0 on Win2008R2, if I want to get the same output from a registry key that “REG QUERY” would give me, in as readable a format, with the values from a particular registry key, like this:
|
1 2 3 4 5 6 7 |
reg query hkcu\Software\Microsoft\CharMap HKEY_CURRENT_USER\Software\Microsoft\CharMap Advanced REG_DWORD 0x0 CodePage REG_SZ Unicode Font REG_SZ Arial |
How would I do that with PowerShell? The behaviour of PowerShell mystifies me, once again.
Get-ItemProperty example:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
Get-ItemProperty HKCU:\Software\Microsoft\CharMap PSPath : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\Software\Microsoft\CharMap PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\Software\Microsoft PSChildName : CharMap PSDrive : HKCU PSProvider : Microsoft.PowerShell.Core\Registry Advanced : 0 CodePage : Unicode Font : Arial |
In my contrived example above, I want to see “Advanced”, “CodePage” and “Font”, but not any of the PowerShell metadata (names starting in PS). Sadly filtering on the name “PS” would not work for me, because I am not REALLY trying to read the MS Windows Character Map settings, I simply chose them as a registry key that probably everyone with Windows has, so everyone can see how utterly different the experience of using PowerShell is to look at the registry, compared to say the REG.EXE program. There are reasons why anybody might want to get just the registry values from a registry key without getting any of the metadata, and anybody writing tools in PowerShell may want to do this simple task.
I would like output similar to REG QUERY but still in native PowerShell format, not just flattened to text. I’ve googled and searched all over and can’t seem to figure this out.
I’d like to be able to for example do this:
|
1 2 3 |
$all = GetRealRegistryKeysFrom( HKCU:\Software\Microsoft\CharMap ) for ($item in $all) { ... } |
Update Using the function below, works great….
Example Get-RegistryKeyPropertiesAndValues -path HKCU:\Software\.....
Answer:
This is a trick:
|
1 2 |
Get-ItemProperty HKCU:\Software\Microsoft\CharMap | out-string -stream | ? { $_ -NOTMATCH '^ps.+' } |
The problem is when a property start with PS . Working on this code you can elaborate to exclude these:
|
1 2 3 4 5 6 |
PSPath PSParentPath PSChildName PSDrive PSProvider |
… One by one inside the where clause. Or just try using
|
1 2 |
get-item hkcu\Software\Microsoft\CharMap |
There a script that do what you need.
update reproduced script here:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
Function Get-RegistryKeyPropertiesAndValues { <# Get-RegistryKeyPropertiesAndValues -path 'HKCU:\Volatile Environment' Http://www.ScriptingGuys.com/blog #> Param( [Parameter(Mandatory=$true)] [string]$path) Push-Location Set-Location -Path $path Get-Item . | Select-Object -ExpandProperty property | ForEach-Object { New-Object psobject -Property @{"property"=$_; "Value" = (Get-ItemProperty -Path . -Name $_).$_}} Pop-Location } #end function Get-RegistryKeyPropertiesAndValues |
