PowerShell synchronization with reg.exe - powershell

I want to set the same values for a large number of registry keys, so I created a PowerShell 2.0 script, to iterate through these keys.
The PowerShell script:
function Main {
param (
[ Parameter( Mandatory = $true ) ] $ScriptInvocation
)
RequireElevation -ScriptInvocation $ScriptInvocation
$ScriptFolder = Split-Path -Parent $ScriptInvocation.MyCommand.Definition
Push-Location -Path $ScriptFolder
ApplyVariants
Pop-Location
}
function RequireElevation {
param (
[ Parameter( Mandatory = $true ) ] $ScriptInvocation
)
$CurrentIdentity = [Security.Principal.WindowsIdentity]::GetCurrent()
$CurrentPrincipal = [Security.Principal.WindowsPrincipal] $CurrentIdentity
$AdministratorRole = [Security.Principal.WindowsBuiltInRole]::Administrator
if( -not $CurrentPrincipal.IsInRole( $AdministratorRole ) ) {
$ScriptPath = $ScriptInvocation.MyCommand.Path
Start-Process -FilePath 'powershell.exe' -ArgumentList '-File', """$ScriptPath""" -Verb RunAs
Exit
}
}
function ApplyVariants {
ApplyVariant -RegFilePath '.\Folder View Per TopView.reg' -Change #{ `
OldString = '{5c4f28b5-f869-4e84-8e60-f11db97c5cc7}\TopViews\{00000000-0000-0000-0000-000000000000}'; `
NewString = '{5c4f28b5-f869-4e84-8e60-f11db97c5cc7}\TopViews\{00000000-0000-0000-0000-000000000000}' }
ApplyVariant -RegFilePath '.\Folder View Per TopView.reg' -Change #{ `
OldString = '{5c4f28b5-f869-4e84-8e60-f11db97c5cc7}\TopViews\{00000000-0000-0000-0000-000000000000}'; `
NewString = '{5f4eab9a-6833-4f61-899d-31cf46979d49}\TopViews\{77f0bfb4-6aa3-440b-9f6d-1c147467806d}' }
ApplyVariant -RegFilePath '.\Folder View Per TopView.reg' -Change #{ `
OldString = '{5c4f28b5-f869-4e84-8e60-f11db97c5cc7}\TopViews\{00000000-0000-0000-0000-000000000000}'; `
NewString = '{5f4eab9a-6833-4f61-899d-31cf46979d49}\TopViews\{82ba0782-5b7a-4569-b5d7-ec83085f08cc}' }
ApplyVariant -RegFilePath '.\Folder View Per TopView.reg' -Change #{ `
OldString = '{5c4f28b5-f869-4e84-8e60-f11db97c5cc7}\TopViews\{00000000-0000-0000-0000-000000000000}'; `
NewString = '{5f4eab9a-6833-4f61-899d-31cf46979d49}\TopViews\{92d203dc-8565-4902-b92c-eaaa54d7364a}' }
# And many, many more ...
}
function ApplyVariant {
param (
[ Parameter( Mandatory = $true ) ] $RegFilePath,
[ Parameter( Mandatory = $true ) ] $Change
)
$TmpFilePath = '.\TemporaryFileCreatedByPowerShell.reg'
$OriginalText = Get-Content -Path $RegFilePath
$VariantText = $OriginalText -replace [Regex]::Escape( $Change.OldString ), $Change.NewString
Set-Content -Path $TmpFilePath -Value $VariantText
# I hope the file is saved before this line
UpdateRegistry -RegFilePath $TmpFilePath
# I hope the file is not required after this line
Remove-Item -Path $TmpFilePath
}
function UpdateRegistry {
param (
[ Parameter( Mandatory = $true ) ] $RegFilePath
)
# Does this really wait?
Start-Process -FilePath 'reg.exe' -ArgumentList 'import', """$RegFilePath""" -Wait
}
Main -ScriptInvocation $MyInvocation
The values I want to set are in this .reg file:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderTypes\{5c4f28b5-f869-4e84-8e60-f11db97c5cc7}\TopViews\{00000000-0000-0000-0000-000000000000}]
"LogicalViewMode"=dword:00000001
"Mode"=-
"IconSize"=-
"HideFileNames"=-
"ColumnList"="prop:0(34)System.ItemNameDisplay;0System.Size;0System.DateModified;0System.DateCreated"
"SortByList"="prop:System.ItemNameDisplay"
"GroupBy"=-
"GroupAscending"=-
"StackBy"=-
"DateCategorizerInfo"=-
"PrimaryProperty"=-
When I run this script, I get no error message. (Even if I add a -NoExit argument to PowerShell's command line.)
However, for some of the keys, the values are not set after running the script. But if I comment out lines in ApplyVariants, and run each line alone, the values for the given key are set.
I suspect that there is some synchronization issue. Maybe the files are deleted before reg.exe could read them.
Is -Wait enough to wait for reg.exe to finish? What can cause this issue?

Pass [switch] inside Start-Job

There is a script for users to log in, it calls other scripts in turn, depending on the conditions.
In order to call scripts separately manually, the [switch]$Silent parameter has been added. Question - how to pass this parameter inside Start-Job? I tried to add to the list of arguments in different ways - the value always falls into the neighboring parameter, regardless of the order.
Main script example
Param(
[string]$location = 'C:\Users',
[switch]$Silent
)
Start-Job -FilePath ".\Fonts_Install.ps1" -ArgumentList ($Silent,$location) | Wait-Job
Fonts_Install.ps1
Param(
[switch]$Silent = $false,
[string]$location = '.'
)
$path_fonts = "$env:LOCALAPPDATA\Microsoft\Windows\Fonts"
$Registry = "HKCU:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts"
function WriteLog {
Param ([string]$LogString)
$Stamp = (Get-Date).toString("yyyy/MM/dd HH:mm:ss")
$LogMessage = "$Stamp $LogString"
Add-content $LogFile -value $LogMessage
}
$Logfile = "$env:LOCALAPPDATA\Temp\fonts_install.log"
WriteLog "Silent $Silent"
WriteLog "location $location"
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName PresentationFramework
Add-Type -AssemblyName System.Drawing
Add-Type -AssemblyName PresentationCore
$SourceFolder = "$location\Fonts_Install"
$WindowsFonts = [System.Drawing.Text.PrivateFontCollection]::new()
$Fonts = Get-ChildItem -Path $SourceFolder -Include *.ttf, *.otf -Recurse -File
ForEach ($Font in $Fonts) {
$Font_Name = $Font.Name
$font_fullname = $Font.fullname
if (Test-Path -PathType Leaf -Path "$path_fonts\$Font_Name") {
WriteLog "Previously installed $Font_Name"
}
else {
Copy-Item $Font -Destination "$path_fonts" -Force -Confirm:$false -PassThru
$WindowsFonts.AddFontFile("$font_fullname")
$ValueFont = "$path_fonts" + "\" + "$Font_Name"
$Typeface = New-Object -TypeName Windows.Media.GlyphTypeface -ArgumentList "$font_fullname"
[string]$FamilyFaceNames = $Typeface.FamilyNames.Values + $Typeface.FaceNames.Values
$RegistryValue = #{
Path = $Registry
Name = $FamilyFaceNames
Value = $ValueFont
}
if (Test-Path $Registry\$FamilyFaceNames) {
Remove-ItemProperty -name $FamilyFaceNames -path $Registry
}
New-ItemProperty #RegistryValue
WriteLog "New fonts installed $Font_Name"
}
}
switch ($Silent) {
$false {
if ($Error.Count -gt 0) {
for ($i = 0; $i -le ($Error.Items.Count + 1); $i++) {
$errMSG = "$Error"
}
[System.Windows.Forms.MessageBox]::Show("$errMSG", "Error", "OK", "Error")
}
else {
[System.Windows.Forms.MessageBox]::Show("ок", "Fonts", "OK", "Asterisk") | out-null
}
}
}
Unfortunately, specifying pass-through arguments via Start-Job's -ArgumentList (-Args) is limited to positional arguments, which prevents binding [switch] parameters, whose arguments must by definition be named.
As a workaround, instead of using -FilePath, invoke your script via the -ScriptBlock parameter. Inside of a script block ({ ... }, named arguments may be used in script calls, as usual:
Start-Job -ScriptBlock {
# Set the current location to the same location as the caller.
# Note: Only needed in *Windows PowerShell*.
Set-Location -LiteralPath ($using:PWD).ProviderPath
.\Fonts_Install.ps1 -Silent:$using:Silent $using:Location
} | Receive-Job -Wait -AutoRemoveJob
Note the use of the $using: scope in order to embed variable values from the caller's scope in the script block that will execute in the background.
You still need to refer to the -Silent parameter by name, and the whether the switch is on or off can be communicated by appending :$true or :$false to it, which is what :$using:Silent does.
In Windows PowerShell, background jobs execute in a fixed location (working directory), namely the user's Documents folder, hence the Set-Location call to explicitly use the same location as the caller, so that the script file can be referenced by a relative path (.\). This is no longer necessary in PowerShell (Core) 7+, which now thankfully uses the same location as the calller.
Here is a different alternative to mklement0's helpful answer, this answer does not use Start-Job and uses a PowerShell instance instead, using this method we can leverage the automatic variable $PSBoundParameters.
Do note, that for this to work properly, both .ps1 scripts must share the same parameter names or Alias Attribute Declarations that matches the same parameter from the caller. See this answer for more details.
You can use these snippets below as a example for you to test how it works.
caller.ps1
param(
[string] $Path = 'C:\Users',
[switch] $Silent
)
try {
if(-not $PSBoundParameters.ContainsKey('Path')) {
$PSBoundParameters['Path'] = $Path
}
$ps = [powershell]::Create().
AddCommand('path\to\myScript.ps1').
AddParameters($PSBoundParameters)
$iasync = $ps.BeginInvoke()
# Do something else here while the .ps1 runs
# ...
# Get async result from the PS Instance
$ps.EndInvoke($iasync)
}
finally {
if($ps -is [IDisposable]) {
$ps.Dispose()
}
}
myScript.ps1
# Note, since we're bounding this parameters from the caller.ps1,
# We don't want to assign Default Values here!
param(
[string] $Path,
[switch] $Silent
)
foreach($param in $MyInvocation.MyCommand.Parameters.Keys) {
[pscustomobject]#{
Parameter = $param
Value = Get-Variable $param -ValueOnly
}
}
A few examples:
PS /> .\caller.ps1
Parameter Value
--------- -----
Path C:\Users
Silent False
PS /> .\caller.ps1 -Path hello
Parameter Value
--------- -----
Path hello
Silent False
PS /> .\caller.ps1 -Path world -Silent
Parameter Value
--------- -----
Path world
Silent True

How can I update a changing value in Powershell in a web.config file?

I am trying to update text inside a web.config file with powershell, but I am having a very, very difficult time.
The problem is this line
<add key="Models.Catalog.Repository" value=Server23 />
You see where the Server23 is? this value sometimes can be empty, which will be represented as "" or sometimes it can have a different name like "\Server25\path"
How do I tell PowerShell to replace/insert data if the field is empty/has some text in it?
here is the full code
$GP_AP= "Server1"
$NewMD = "\\JohnWick"
Invoke-Command -ComputerName $GP_AP -ScriptBlock {
$date= Get-Date -Format "dd_MM_yyyy_HHMM_ss"
$webfile = "C:\Program Files\TEST\IIS\Web.config"
(Copy-Item -Path $webfile -Destination $webfile_Test_$Date)
#[xml]$webconfigfile = Get-Content "C:\Program Files\TEST\IIS\Web.config"
#[xml]$2 = Get-Content "\\Server1\C$\Program Files\TEST\IIS\Web.config"
$olddata = "*"
#(Get-Content $webfile -raw).Replace("<add key=`"Models.Catalog.Repository`" value=$olddata />","<add key=`"Models.Catalog.Repository`" value=$Using:NewMD />") `
#| Set-Content "C:\Program Files\TEST\IIS\Web.config" -Force -Encoding UTF8 -ErrorAction Stop
(Get-Content $webfile -raw).Replace('<add key="Models.Catalog.Repository" value=Server23 />',"<add key=`"Models.Catalog.Repository`" value=$Using:NewMD />") `
| Set-Content "C:\Program Files\TEST\IIS\Web.config" -Force -Encoding UTF8 -ErrorAction Stop
} # end of script block
The script below will allow you to set values in a web config's <appSettings> based on key names. All the nodes must exist. This script will not create them. You'll obviously need to edit the script's default params.
param(
[string] $pathToWebConfig = "$PSScriptRoot\web.config"
[System.Collections.Hashtable] $appSettings = #{
someKey = 'somevalue';
someOtherKey = 'someOtherValue'
}
)
function UpdateXmlConfigAppSettings(
[Parameter(mandatory=$true)]
[string] $configFilePath,
[Parameter(mandatory=$true)]
[System.Collections.Hashtable] $appSettingsDict
) {
[xml] $webConfig = Get-Content $configFilePath
foreach($key in $appSettingsDict.Keys) {
$node = $webConfig.SelectSingleNode("//appSettings/add[#key = '$key']")
if ($null -ne $node) {
$node.SetAttribute('value', $appSettingsDict[$key])
}
else {
throw "$appSettingsDict[$key] is not a valid key in AppSettings"
}
}
$webConfig.Save($configFilePath)
}
UpdateXmlConfigAppSettings -configFilePath $pathToWebConfig -appSettingsDict $appSettings
$path = '\\server\c$\Program Files\TEST\IIS\web.config'
[xml]$config = Get-Content -Path $path -Raw
$stuffIwant = "\\Blah-244"
$config.SelectNodes("//add[#key='Models.Catalog.Repository']") | `
ForEach-Object { $_.SetAttribute("value", $stuffIwant) }
$config.Save($path)

installing msi file using powershell bringing up command line options

I am trying to run the below command and it opens windows installers parameters, what am I doing wrong?
$current_pc = "$env:computername"
$filePath = "c:\users\ArA\Desktop\parameters.csv"
$machineParams = Import-CSV $filePath
$info = if($machineParams){$machineParams | where {$_.branch -eq $($current_pc.Substring($current_pc.length - 3,3))}}
else{write-output "CSV not loaded"}
$info
start-process msiexec.exe -Wait -ArgumentList /L* "c:\users\Ara\Desktop\t.log" /qn /I "c:\users\Ar\Desktop\setup.msi" DATABASE_ID=$($info.DATABASE_ID),ODBC_DATABASE_NAME=$($info.ODBC_DATABASE_NAME),ODBC_ENGINE_NAME=$($info.ODBC_ENGINE_NAME) ODBC_HOST_NAME=$($info.ODBC_HOST_NAME) NOLAN=1
It's likely how you are passing your arguments. As a best-practice, I utilize an array when passing exe arguments so they're interpreted properly:
$machineParams = Import-Csv -Path $Env:UserProfile\Desktop\parameters.csv
$info = if ($machineParams) {
$machineParams |
Where-Object { $_.branch -eq $Env:ComputerName.Substring($Env:ComputerName.Length - 3, 3) }
} else {
'CSV not loaded.'
}
$info
$StartArgs = #{
'Wait' = $true
'FilePath' = "$Env:SystemRoot\System32\msiexec.exe"
'ArgumentList' = #(
'/i',"$Env:UserProfile\Desktop\setup.msi"
'/qn'
'/log',"$Env:UserProfile\Desktop\t.log"
)
}
if ($info -ne 'CSV not loaded.') {
$StartArgs['ArgumentList'] += #(
"DATABASE_ID=$($info.DATABASE_ID)"
"ODBC_DATABASE_NAME=$($info.ODBC_DATABASE_NAME)"
"ODBC_ENGINE_NAME=$($info.ODBC_ENGINE_NAME)"
"ODBC_HOST_NAME=$($info.ODBC_HOST_NAME)"
'NOLAN=1'
)
}
Start-Process #StartArgs

Dynamic Parameters - with Dynamic ValidateSet

I have a script that I've been working on to provide parsing of SCCM log files. This script takes a computername and a location on disk to build a dynamic parameter list and then present it to the user to choose the log file they want to parse. Trouble is I cannot seem to get the ValidateSet portion of the dynamic parameter to provide values to the user. In addition the script won't display the -log dynamic parameter when attempting to call the function.
When you run it for the first time you are not presented with the dynamic parameter Log as I mentioned above. If you then use -log and then hit tab you’ll get the command completer for the files in the directory you are in. Not what you’d expect; you'd expect that it would present you the Logfile names that were gathered during the dynamic parameter execution.
PSVersion 5.1.14409.1012
So the question is how do I get PowerShell to present the proper Validate set items to the user?
If you issue one of the items in the error log you get the proper behavior:
Here are the two functions that i use to make this possible:
function Get-CCMLog
{
[CmdletBinding()]
param([Parameter(Mandatory=$true,Position=0)]$ComputerName = '$env:computername', [Parameter(Mandatory=$true,Position=1)]$path = 'c:\windows\ccm\logs')
DynamicParam
{
$ParameterName = 'Log'
if($path.ToCharArray() -contains ':')
{
$FilePath = "\\$ComputerName\$($path -replace ':','$')"
if(test-path $FilePath)
{
$logs = gci "$FilePath\*.log"
$LogNames = $logs.basename
$logAttribute = New-Object System.Management.Automation.ParameterAttribute
$logAttribute.Position = 2
$logAttribute.Mandatory = $true
$logAttribute.HelpMessage = 'Pick A log to parse'
$logCollection = New-Object System.Collections.ObjectModel.Collection[System.Attribute]
$logCollection.add($logAttribute)
$logValidateSet = New-Object System.Management.Automation.ValidateSetAttribute($LogNames)
$logCollection.add($logValidateSet)
$logParam = New-Object System.Management.Automation.RuntimeDefinedParameter($ParameterName,[string],$logCollection)
$logDictionary = New-Object System.Management.Automation.RuntimeDefinedParameterDictionary
$logDictionary.Add($ParameterName,$logParam)
return $logDictionary
}
}
}
begin {
# Bind the parameter to a friendly variable
$Log = $PsBoundParameters[$ParameterName]
}
process {
# Your code goes here
#dir -Path $Path
$sb2 = "$((Get-ChildItem function:get-cmlog).scriptblock)`r`n"
$sb1 = [scriptblock]::Create($sb2)
$results = Invoke-Command -ComputerName $ComputerName -ScriptBlock $sb1 -ArgumentList "$path\$log.log"
[PSCustomObject]#{"$($log)Log"=$results}
}
}
function Get-CMLog
{
param(
[Parameter(Mandatory=$true,
Position=0,
ValueFromPipelineByPropertyName=$true)]
[Alias("FullName")]
$Path,
$tail =10
)
PROCESS
{
if(($Path -isnot [array]) -and (test-path $Path -PathType Container) )
{
$Path = Get-ChildItem "$path\*.log"
}
foreach ($File in $Path)
{
if(!( test-path $file))
{
$Path +=(Get-ChildItem "$file*.log").fullname
}
$FileName = Split-Path -Path $File -Leaf
if($tail)
{
$lines = Get-Content -Path $File -tail $tail
}
else {
$lines = get-cotnet -path $file
}
ForEach($l in $lines ){
$l -match '\<\!\[LOG\[(?<Message>.*)?\]LOG\]\!\>\<time=\"(?<Time>.+)(?<TZAdjust>[+|-])(?<TZOffset>\d{2,3})\"\s+date=\"(?<Date>.+)?\"\s+component=\"(?<Component>.+)?\"\s+context="(?<Context>.*)?\"\s+type=\"(?<Type>\d)?\"\s+thread=\"(?<TID>\d+)?\"\s+file=\"(?<Reference>.+)?\"\>' | Out-Null
if($matches)
{
$UTCTime = [datetime]::ParseExact($("$($matches.date) $($matches.time)$($matches.TZAdjust)$($matches.TZOffset/60)"),"MM-dd-yyyy HH:mm:ss.fffz", $null, "AdjustToUniversal")
$LocalTime = [datetime]::ParseExact($("$($matches.date) $($matches.time)"),"MM-dd-yyyy HH:mm:ss.fff", $null)
}
[pscustomobject]#{
UTCTime = $UTCTime
LocalTime = $LocalTime
FileName = $FileName
Component = $matches.component
Context = $matches.context
Type = $matches.type
TID = $matches.TI
Reference = $matches.reference
Message = $matches.message
}
}
}
}
}
The problem is that you have all the dynamic logic inside scriptblock in the if statement, and it handles the parameter addition only if the path provided contains a semicolon (':').
You could change it to something like:
if($path.ToCharArray() -contains ':') {
$FilePath = "\\$ComputerName\$($path -replace ':','$')"
} else {
$FilePath = $path
}
and continue your code from there

What essential things (functions, aliases, start up scripts) do you have in your profile?
I often find myself needing needing some basic agregates to count/sum some things., I've defined these functions and use them often, they work really nicely at the end of a pipeline :
#
# useful agregate
#
function count
{
BEGIN { $x = 0 }
PROCESS { $x += 1 }
END { $x }
}
function product
{
BEGIN { $x = 1 }
PROCESS { $x *= $_ }
END { $x }
}
function sum
{
BEGIN { $x = 0 }
PROCESS { $x += $_ }
END { $x }
}
function average
{
BEGIN { $max = 0; $curr = 0 }
PROCESS { $max += $_; $curr += 1 }
END { $max / $curr }
}
To be able to get time and path with colors in my prompt :
function Get-Time { return $(get-date | foreach { $_.ToLongTimeString() } ) }
function prompt
{
# Write the time
write-host "[" -noNewLine
write-host $(Get-Time) -foreground yellow -noNewLine
write-host "] " -noNewLine
# Write the path
write-host $($(Get-Location).Path.replace($home,"~").replace("\","/")) -foreground green -noNewLine
write-host $(if ($nestedpromptlevel -ge 1) { '>>' }) -noNewLine
return "> "
}
The following functions are stolen from a blog and modified to fit my taste, but ls with colors is very nice :
# LS.MSH
# Colorized LS function replacement
# /\/\o\/\/ 2006
# http://mow001.blogspot.com
function LL
{
param ($dir = ".", $all = $false)
$origFg = $host.ui.rawui.foregroundColor
if ( $all ) { $toList = ls -force $dir }
else { $toList = ls $dir }
foreach ($Item in $toList)
{
Switch ($Item.Extension)
{
".Exe" {$host.ui.rawui.foregroundColor = "Yellow"}
".cmd" {$host.ui.rawui.foregroundColor = "Red"}
".msh" {$host.ui.rawui.foregroundColor = "Red"}
".vbs" {$host.ui.rawui.foregroundColor = "Red"}
Default {$host.ui.rawui.foregroundColor = $origFg}
}
if ($item.Mode.StartsWith("d")) {$host.ui.rawui.foregroundColor = "Green"}
$item
}
$host.ui.rawui.foregroundColor = $origFg
}
function lla
{
param ( $dir=".")
ll $dir $true
}
function la { ls -force }
And some shortcuts to avoid really repetitive filtering tasks :
# behave like a grep command
# but work on objects, used
# to be still be allowed to use grep
filter match( $reg )
{
if ($_.tostring() -match $reg)
{ $_ }
}
# behave like a grep -v command
# but work on objects
filter exclude( $reg )
{
if (-not ($_.tostring() -match $reg))
{ $_ }
}
# behave like match but use only -like
filter like( $glob )
{
if ($_.toString() -like $glob)
{ $_ }
}
filter unlike( $glob )
{
if (-not ($_.tostring() -like $glob))
{ $_ }
}
This iterates through a scripts PSDrive and dot-sources everything that begins with "lib-".

To setup my Visual Studio build environment from PowerShell I took the VsVars32 from here. and use it all the time.
###############################################################################
# Exposes the environment vars in a batch and sets them in this PS session
###############################################################################
function Get-Batchfile($file)
{
$theCmd = "`"$file`" & set"
cmd /c $theCmd | Foreach-Object {
$thePath, $theValue = $_.split('=')
Set-Item -path env:$thePath -value $theValue
}
}
###############################################################################
# Sets the VS variables for this PS session to use
###############################################################################
function VsVars32($version = "9.0")
{
$theKey = "HKLM:SOFTWARE\Microsoft\VisualStudio\" + $version
$theVsKey = get-ItemProperty $theKey
$theVsInstallPath = [System.IO.Path]::GetDirectoryName($theVsKey.InstallDir)
$theVsToolsDir = [System.IO.Path]::GetDirectoryName($theVsInstallPath)
$theVsToolsDir = [System.IO.Path]::Combine($theVsToolsDir, "Tools")
$theBatchFile = [System.IO.Path]::Combine($theVsToolsDir, "vsvars32.bat")
Get-Batchfile $theBatchFile
[System.Console]::Title = "Visual Studio " + $version + " Windows Powershell"
}
start-transcript. This will write out your entire session to a text file. Great for training new hires on how to use Powershell in the environment.
My prompt contains:
$width = ($Host.UI.RawUI.WindowSize.Width - 2 - $(Get-Location).ToString().Length)
$hr = New-Object System.String #('-',$width)
Write-Host -ForegroundColor Red $(Get-Location) $hr
Which gives me a divider between commands that's easy to see when scrolling back. It also shows me the current directory without using horizontal space on the line that I'm typing on.
For example:
C:\Users\Jay ----------------------------------------------------------------------------------------------------------
[1] PS>

# msdn search for win32 APIs.
# ----------------------------------------------------------
function Search-MSDNWin32
{

}

The mandatory anything I can PowerShell I will functions go here...
# Explorer command
function Explore
{
param
(
[Parameter(
Position = 0,
ValueFromPipeline = $true,

HelpMessage = "This is the path to explore..."
)]
[ValidateNotNullOrEmpty()]
[string]
# First parameter is the path you're going to explore.
$Target
)
$exploration = New-Object -ComObject shell.application
$exploration.Explore($Target)
}
I am STILL an administrator so I do need...
Function RDP
{
param
(
[Parameter(
Position = 0,
ValueFromPipeline = $true,
Mandatory = $true,
HelpMessage = "Server Friendly name"
)]
[ValidateNotNullOrEmpty()]
[string]
$server
)
cmdkey /generic:TERMSRV/$server /user:$UserName /pass:($Password.GetNetworkCredential().Password)
mstsc /v:$Server /f /admin
Wait-Event -Timeout 5
cmdkey /Delete:TERMSRV/$server
}
Sometimes I want to start explorer as someone other than the logged in user...
# Restarts explorer as the user in $UserName
function New-Explorer
{
# CLI prompt for password
taskkill /f /IM Explorer.exe
runas /noprofile /netonly /user:$UserName explorer
}
This is just because it's funny.
Function Lock-RemoteWorkstation

param(
$Computername,
$Credential
)
if(!(get-module taskscheduler))
{
Import-Module TaskScheduler
}
New-task -ComputerName $Computername -credential:$Credential |

I also have one for me, since Win + L is too far away...

public static extern bool LockWorkStation();
"#

}
A few filters? I think so...
filter FileSizeBelow($size){if($_.length -le $size){ $_ }}
filter FileSizeAbove($size){if($_.Length -ge $size){$_}}
I also have a few I can't post yet, because they're not done but they're basically a way to persist credentials between sessions without writing them out as an encrypted file.

Although I think this has been superseded by a recent or upcoming release.

I keep a little bit of everything. Mostly, my profile sets up all the environment (including calling scripts to set up my .NET/VS and Java development environment).
I also redefine the prompt() function with my own style (see it in action), set up several aliases to other scripts and commands. and change what $HOME points to.
Here's my complete profile script.
Set-PSDebug -Strict
You will benefit i you ever searched for a stupid Typo eg. outputting $varsometext instead $var sometext
##############################################################################
# Get an XPath Navigator object based on the input string containing xml
function get-xpn ($text) {
$rdr = [System.IO.StringReader] $text
$trdr = [system.io.textreader]$rdr
$xpdoc = [System.XML.XPath.XPathDocument] $trdr
$xpdoc.CreateNavigator()
}
Useful for working with xml, such as output from svn commands with --xml.
This creates a scripts: drive and adds it to your path. Note, you must create the folder yourself. Next time you need to get back to it, just type "scripts:" and hit enter, just like any drive letter in Windows.
$env:path += ";$profiledir\scripts"
New-PSDrive -Name Scripts -PSProvider FileSystem -Root $profiledir\scripts
This will add snapins you have installed into your powershell session. The reason you may want to do something like this is that it's easy to maintain, and works well if you sync your profile across multiple systems. If a snapin isn't installed, you won't see an error message.
---------------------------------------------------------------------------
Add third-party snapins
---------------------------------------------------------------------------
$snapins = #(
"Quest.ActiveRoles.ADManagement",
"PowerGadgets",
"VMware.VimAutomation.Core",
"NetCmdlets"
)
$snapins | ForEach-Object {
if ( Get-PSSnapin -Registered $_ -ErrorAction SilentlyContinue ) {
Add-PSSnapin $_
}
}
I put all my functions and aliases in separate script files and then dot source them in my profile:
. c:\scripts\posh\jdh-functions.ps1
The function to view the entire history of typed command (Get-History, and his alias h show default only 32 last commands):
function ha {
Get-History -count $MaximumHistoryCount
}
You can see my PowerShell profile at http://github.com/jamesottaway/windowspowershell
If you use Git to clone my repo into your Documents folder (or whatever folder is above 'WindowsPowerShell' in your $PROFILE variable), you'll get all of my goodness.
The main profile.ps1 sets the subfolder with the name Addons as a PSDrive, and then finds all .ps1 files underneath that folder to load.
I quite like the go command, which stores a dictionary of shorthand locations to visit easily. For example, go vsp will take me to C:\Visual Studio 2008\Projects.
I also like overriding the Set-Location cmdlet to run both Set-Location and Get-ChildItem.
My other favourite is being able to do a mkdir which does Set-Location xyz after running New-Item xyz -Type Directory.
amongst many other things:
function w {
explorer .
}
opens an explorer window in the current directory
function startover {
iisreset /restart
iisreset /stop
rm "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\*.*" -recurse -force -Verbose
iisreset /start
}
gets rid of everything in my temporary asp.net files (useful for working on managed code that has dependencies on buggy unmanaged code)
function edit($x) {
. 'C:\Program Files (x86)\Notepad++\notepad++.exe' $x
}
edits $x in notepad++
I actually keep mine on github.

Only a sagaciously-lazy individual would tell you that fop is so much easier to type than Notepad $PROFILE at the prompt, unless, of course, you associate "fop" with a 17th century English ninny.
If you wanted, you could take it a step further and make it somewhat useful:
Function funcOpenPowerShellProfile

$fileProfileBackup = $PROFILE + '.bak'
cp $PROFILE $fileProfileBackup
PowerShell_ISE $PROFILE # Replace with Desired IDE/ISE for Syntax Highlighting
}

$fileProfileHostPath = $fileProfilePathParts[$fileProfilePathPartNum] + '\'
$fileProfileHostPathPartsCount = $fileProfilePathParts.Count - 2
# Arrays start at 0, but the Count starts at 1; if both started at 0 or 1,
# then a -1 would be fine, but the realized discrepancy is 2

I keep my profile empty. Instead, I have folders of scripts I can navigate to load functionality and aliases into the session. A folder will be modular, with libraries of functions and assemblies. For ad hoc work, I'll have a script to loads aliases and functions. If I want to munge event logs, I'd navigate to a folder scripts\eventlogs and execute
PS > . .\DotSourceThisToLoadSomeHandyEventLogMonitoringFunctions.ps1
I do this because I need to share scripts with others or move them from machine to machine. I like to be able to copy a folder of scripts and assemblies and have it just work on any machine for any user.
But you want a fun collection of tricks. Here's a script that many of my "profiles" depend on. It allows calls to web services that use self signed SSL for ad hoc exploration of web services in development. Yes, I freely mix C# in my powershell scripts.
# Using a target web service that requires SSL, but server is self-signed.
# Without this, we'll fail unable to establish trust relationship.
function Set-CertificateValidationCallback
{
try
{
Add-Type #'
using System;
public static class CertificateAcceptor{
public static void SetAccept()
{
System.Net.ServicePointManager.ServerCertificateValidationCallback = AcceptCertificate;
}
private static bool AcceptCertificate(Object sender,
System.Security.Cryptography.X509Certificates.X509Certificate certificate,
System.Security.Cryptography.X509Certificates.X509Chain chain,
System.Net.Security.SslPolicyErrors policyErrors)
{
Console.WriteLine("Accepting certificate and ignoring any SSL errors.");
return true;
}
}
'#
}
catch {} # Already exists? Find a better way to check.
[CertificateAcceptor]::SetAccept()
}
Great question. Because I deal with several different PowerShell hosts, I do a little logging in each of several profiles, just to make the context of any other messages clearer. In profile.ps1, I currently only have that, but I sometimes change it based on context:
if ($PSVersionTable.PsVersion.Major -ge 3) {
Write-Host "Executing $PSCommandPath"
}
My favorite host is the ISE, in Microsoft.PowerShellIse_profile.ps1, I have:
if ($PSVersionTable.PsVersion.Major -ge 3) {
Write-Host "Executing $PSCommandPath"
}
if ( New-PSDrive -ErrorAction Ignore One FileSystem `
(Get-ItemProperty hkcu:\Software\Microsoft\SkyDrive UserFolder).UserFolder) {
Write-Host -ForegroundColor Green "PSDrive One: mapped to local OneDrive/SkyDrive folder"
}
Import-Module PSCX
$PSCX:TextEditor = (get-command Powershell_ISE).Path
$PSDefaultParameterValues = #{
"Get-Help:ShowWindow" = $true
"Help:ShowWindow" = $true
"Out-Default:OutVariable" = "0"
}

Of everything not already listed, Start-Steroids has to be my favorite, except for maybe Start-Transcript.
