PowerShell Script Loop Through Each File And Do A Find And Replace - powershell

My Current Code Is
Param(
[string]$filePath = "C:\",
[string]$logFileFind = "error.log",
[string]$logFileReplace ="ThisHasBeenReplaced.log"
)
($configFile = Get-ChildItem -Recurse -Force $filePath -ErrorAction SilentlyContinue | Where-Object { ($_.PSIsContainer -eq $false) -and ( $_.Name -like "*.config") }
It Works fine and gives me list of files i was wondering how i could go through these files and find and replace certain words for when I'm moving though environments and the path wont be the same. I'm very limited in my powershell knowledge and i tried adding this to the end of the script.
ForEach-Object{(Get-Content $configFile) -replace $logFileFind , $logFileReplace | Set-Content $configFile})
This didn't work and i was wondering if there was anyone out there who knew what i could do to make it work.
Thanks in Advance!

You always access $configFile in your foreach loop (which is probably an System.Array), not the actual element. Try this:
$configFile | foreach { (get-content $_.FullName -Raw) -replace $logFileFind , $logFileReplace | Set-Content $_.FullName }
Here is a full example:
Get-ChildItem -Recurse -force $filePath -ea 0 |
where { ($_.PSIsContainer -eq $false) -and ( $_.Name -like "*.config") } |
foreach {
(gc $_.FullName -raw) -replace $logFileFind , $logFileReplace | sc $_.FullName
}

empty var in compare-object | powershell

im quiet new to powerhsell and I have the following goal:
My code is supposed to loop through selected subfolders and compare those. The names of the subfolders are identical in both parent folders, however the path before those selected folders are different: C:\temp\parentF1\BackUp* and C:\temp\parentF2\BackUp*
The problem that I have is that even tho I think my $vars that I use for the comparison should have a value, are NULL and I cant think of why!
$path = "subfolder1","subfolder2","subfolder3"
$excludeF1 = #(C:\temp\parentF1\BackUp\*\subfolder5)
$excludeF2 = #(C:\temp\parentF2\BackUp\*\subfolder5)
$x = 0
while($x -lt $path.Count){
$F1 = Get-ChildItem -Recurse -Path "C:\temp\parentF1\BackUp\$path[$x]" |
Where-Object {$_.FullName -notlike $excludeF1}
$F2 = Get-ChildItem -Recurse -Path "C:\temp\parentF2\BackUp\$path[$x]" |
Where-Object {$_.FullName -notlike $excludeF2}
Compare-Object -ref $F1 -dif $F2 |
Select-Object #{Label="$path[$x]";e={$_.InputObject}},`
#{n="Fundort";e={if($_.SideIndicator -like "=>") {write-output "BackUp F1"}`
elseif($_.SideIndicator -like "<="){Write-Output "BackUp F2"}}} | Out-File dif.txt
$x++
}
start .\dif.txt
also the out-file cmdlet doesnt work but that`s a dif topic
Thanks for any help in advance
This does not work as you expect:
Get-ChildItem ... -Path "C:\temp\parentF1\BackUp\$path[$x]"
When using -Path, PowerShell interprets [...] as part of its own wildcard syntax. Use -LiteralPath to prevent that.
Anything more complex than simple variable name ($var) must be enclosed in a subexpression $(...).
Similar issue:
Select-Object #{Label="$path[$x]"; ...
This can be solved by simply removing the quotation, as $path already contains strings.
Solution:
$F1 = Get-ChildItem -Recurse -LiteralPath "C:\temp\parentF1\BackUp\$($path[$x])" | ...
$F2 = Get-ChildItem -Recurse -LiteralPath "C:\temp\parentF2\BackUp\$($path[$x])" | ...
Compare-Object ... |
Select-Object #{Label=$path[$x]; ...
The above fixes your current code, but your code could be simplified like this to avoid the subexpressions:
foreach($currentPath in $path) {
$F1 = Get-ChildItem -Recurse -Path "C:\temp\parentF1\BackUp\$currentPath" |
Where-Object FullName -notlike $excludeF1
$F2 = Get-ChildItem -Recurse -Path "C:\temp\parentF2\BackUp\$currentPath" |
Where-Object FullName -notlike $excludeF2
Compare-Object -ref $F1 -dif $F2 |
Select-Object #{Label=$currentPath;e={$_.InputObject}},`
#{n="Fundort";e={if($_.SideIndicator -like "=>") {write-output "BackUp F1"}`
elseif($_.SideIndicator -like "<="){Write-Output "BackUp F2"}}} | Out-File dif.txt
}

command 'search-index' does not appear to be working

here is the script I've created. I have downloaded the 'PSSearch' package and when I goto commands 'Search-Index' is one of the available commands
$computers = #([some computer])
$destination = "[some path]"
foreach ($computer in $computers) {
$Path = Set-Location [path on computer]
$keywords= #('"word 1"','word2','word3','word4')
$dirlist = Get-ChildItem -Recurse -Force $Path -ErrorAction Continue
foreach($word in $keywords) {
$SearchResults = Search-Index $word
$dirlist | Where-Object {$_.Name -match $SearchResults} | Select-Object Name,FullName | format-Table * -AutoSize |
Export-Csv $destination\FoundFiles.csv -nti -Append
$cui = ($dirlist | Where-Object {$_.Name -match $SearchResults})
Copy-Item $cui -Destination $destination - Append
}
}
What is happening is I'm getting all files and folders from the location (not just the ones I'm searching for)
The problem could be that I don't know how this line should be scripted
$cui = ($dirlist | Where-Object {$_.Name -match $SearchResults})

I am trying to get the files in zip format which were newly created around two days ago using powershell and I am not getting any output

$Servers = Get-content 'D:\utils\Backup\SBX servers.txt'
foreach($Path in $Servers){
$Path = "E:\Backup"
$result = Get-ChildItem E:\Backup\*_DB.zip -Recurse -Force -File |Format-Wide| Where-Object { $_.LastWriteTime -gt (get-date).AddDays(-1)}
$result
}
you were not far from the solution, but there are multiple problem with your syntax. First you should not "filter" (where-object), after "formating" (Format-wide).
foreach($Path in $Servers){
$Path = "E:\Backup"
$result = Get-ChildItem E:\Backup*DB.zip -Recurse -Force -File | Where-Object { $_.LastWriteTime -gt (get-date).AddDays(-1)}
$result | Format-Wide
}
you were missing the "underscore" in your filter too: "$." -> "$_."

PowerShell - Copy-item with -passThru to post process files

Newbie stuck doing the basics.
I'm trying to copy files from A to B & then replace text within each file copied. Pretty basic - but it fails What am I doing wrong? Any assistance would be welcome - please. nb I believe I need to use copy-item, alternatives okay as long as same result.
$files = Copy-Item -Path "C:\from" -Filter *.* -Recurse -Destination "C:\to" -Force -PassThru
foreach ($file in $files) {
Get-Item $file |
Where-Object {-not $_.PsIsContainer} |
(Get-Content .) |
Foreach-Object {
$_ -replace ( "maskkey", $maskvalue} |
Set-Content $file
}
}
You need to move the get-content part within the foreach-object script block, and use $_ instead of .
So, something like this:
foreach($file in $files){
Get-Item $file | Where-Object {-not ($_.PsIsContainer)} | Foreach-Object{
$content = Get-Content $_
$newContent = $content.replace("maskkey", $maskvalue)
Set-Content -Value $newContent -Path $file
}
}
Note. I haven't actually tested this code, but you should at least have the basic structure right.

Replace multiple strings in a file using powershell

I am using following coe to replace the string
$folders=Get-ChildItem -Path "C:\temp\Database Scripts"
foreach($folder in $folders)
{
Write-Host $folder
$spath=[string]::Concat("C:\temp\Database Scripts\", $folder)
$subfolders=Get-ChildItem $spath
foreach($subfolder in $subfolders )
{
if($subfolder -match "Running Scripts")
{
$subfolerpath=[string]::Concat($spath,"\",$subfolder,"\*")
$files =get-childitem -Path $subfolerpath -include "AVEVAScripts*"
if($files -ne $null)
{
foreach( $file in $files)
{
Write-Host $file;
(Get-Content $file) | ForEach-Object {$_ -replace "DATABASE_USER","fhghjgj" `
-replace "DATABASE_PASSWORD", "DFGHFHJGJH" } |Set-Content $file
}
}
}
}
}
But ending up with following error.
Set-Content : The input object cannot be bound to any parameters for the command either because the command does not take pipeline input or the input and its properties do not match any of the parameters that take pipeline input.
Please help :)
Remove the $x in the end of Set-Content. $x is never declared.
Also, you could simplify it a lot. Ex:
Get-ChildItem -Filter "Running Scripts" -Path "C:\temp\Database Scripts" -Recurse | ForEach-Object {
Get-ChildItem -Path $_.FullName -Filter "AVEVAScripts*" -Recurse | ForEach-Object {
(Get-Content $_.FullName) | ForEach-Object {
$_ -replace "DATABASE_USER","fhghjgj" -replace "DATABASE_PASSWORD", "DFGHFHJGJH"
} | Set-Content $_.FullName
}
}
Or find all files that includes "AVEVAScripts" in it's name, then check if their full path includes "Running Scripts"
Get-ChildItem -Filter "AVEVAScripts*" -Path "C:\temp\Database Scripts" -Recurse |
Where-Object { $_.FullName -like "*Running Scripts*" } |
ForEach-Object {
(Get-Content $_.FullName) | ForEach-Object {
$_ -replace "DATABASE_USER","fhghjgj" -replace "DATABASE_PASSWORD", "DFGHFHJGJH"
} | Set-Content $_.FullName
}
