Powershell: Replace strings in all .ini files recursively - powershell

Question

I've been wanting an easy to use script that will allow me to replace multiple strings from multiple files for a while. So far I've got this code:
$replacements = #{
'bCompressDiffuseLocalPlayerCharacterTextures=True' = 'bCompressDiffuseLocalPlayerCharacterTextures=False'
'bCompressDiffuseLocalPlayerVehicleTextures=True' = 'bCompressDiffuseLocalPlayerVehicleTextures=False'
'bCompressDiffuseOtherPlayerCharacterTextures=True' = 'bCompressDiffuseOtherPlayerCharacterTextures=False'
'bCompressDiffuseOtherPlayerVehicleTextures=True' = 'bCompressDiffuseOtherPlayerVehicleTextures=False'
'bCompressNormalTextures=True' = 'bCompressNormalTextures=False'
'bDisablePhysXHardwareSupport=True' = 'bDisablePhysXHardwareSupport=False'
'bEnableMouseSmoothing=True' = 'bEnableMouseSmoothing=False'
'bInitializeShadersOnDemand=True' = 'bInitializeShadersOnDemand=False'
'MaxChannels=32' = 'MaxChannels=64'
'MotionBlur=True' = 'MotionBlur=False'
'm_bCalculateOnServer=True' = 'm_bCalculateOnServer=False'
'OneFrameThreadLag=True' = 'OneFrameThreadLag=False'
'PoolSize=140' = 'PoolSize=1024'
'UseMinimalNVIDIADriverShaderOptimization=True' = 'UseMinimalNVIDIADriverShaderOptimization=False'
'UseTextureFileCache=False' = 'UseTextureFileCache=True'
}
function Update-FileContent {
[cmdletbinding()]
param(
[Parameter(ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true,
Mandatory=$true,
Position=0)]
[Alias('PsPath')]
$Path
)
$lines = Get-Content $Path
$lines | ForEach-Object {
foreach($rep in $replacements.Keys)
{
$_ = $_ -replace $rep, $replacements[$rep]
}
$_
} | Set-Content $Path
}
Get-ChildItem -Recurse *.ini | Update-FileContent
It works but only if a file is 1 directory deep.

I'd do something like this:
$replacements = #{
'bCompressDiffuseLocalPlayerCharacterTextures=True' = 'bCompressDiffuseLocalPlayerCharacterTextures=False'
'bCompressDiffuseLocalPlayerVehicleTextures=True' = 'bCompressDiffuseLocalPlayerVehicleTextures=False'
'bCompressDiffuseOtherPlayerCharacterTextures=True' = 'bCompressDiffuseOtherPlayerCharacterTextures=False'
'bCompressDiffuseOtherPlayerVehicleTextures=True' = 'bCompressDiffuseOtherPlayerVehicleTextures=False'
'bCompressNormalTextures=True' = 'bCompressNormalTextures=False'
'bDisablePhysXHardwareSupport=True' = 'bDisablePhysXHardwareSupport=False'
'bEnableMouseSmoothing=True' = 'bEnableMouseSmoothing=False'
'bInitializeShadersOnDemand=True' = 'bInitializeShadersOnDemand=False'
'MaxChannels=32' = 'MaxChannels=64'
'MotionBlur=True' = 'MotionBlur=False'
'm_bCalculateOnServer=True' = 'm_bCalculateOnServer=False'
'OneFrameThreadLag=True' = 'OneFrameThreadLag=False'
'PoolSize=140' = 'PoolSize=1024'
'UseMinimalNVIDIADriverShaderOptimization=True' = 'UseMinimalNVIDIADriverShaderOptimization=False'
'UseTextureFileCache=False' = 'UseTextureFileCache=True'
}
function Update-FileContent {
[cmdletbinding()]
param(
[Parameter(ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true, Mandatory=$true, Position=0)]
[Alias('PsPath')]
$Path
)
# read the ini file in as one single string
$content = Get-Content $Path -Raw
# copy that string so we can compare at the end of the loop if anything has changed at all
$newContent = $content
foreach($rep in $replacements.Keys) {
$newContent = $newContent -replace $rep, $replacements[$rep]
}
# only replace the contents of the ini file if changes are made
if ($newContent -ne $content) {
Write-Host "Replacing content of file '$Path'"
Set-Content $Path -Value $content
}
}
$rootPath = '<PATH OF THE ROOTFOLDER TO RECURSE WHERE THE INI FILES ARE LOCATED>'
Get-ChildItem -Path $rootPath -Filter '*.ini' -Recurse | ForEach-Object { Update-FileContent $_.FullName }
