Tweak PS script to delete server name

PowerShell Help
1

Hello,

I have below script to input server host name or IP which returns the text files for those host names/IP as output.

Then i have to manually delete those host names from the text files.

How can I tweak the script to directly delete that host name from text file and save it ? Also instead of one host name as input can we put down a list of servers to search and delete with success/failure log ?

If someone can suggest how to achieve this.

Thanks .

[string]$Server = Read-Host -Prompt ‘Input the server name to search and hit Enter’
#[string]$Path1 = \servername.com\d$
[string]$Path = “\servername.com\d$”

#Do {

write-host $Server
write-host “Searching for the Server $Server in $Path …search is in progress… `n `n” -foregroundcolor green

$PathArray = @()

$Time = (Measure-Command {

Get-ChildItem $Path -recurse -Filter “*.txt” | Where-Object {$.Name -notmatch “backup”,“Notes”,“test”,“copy”} |
Where-Object { $.Attributes -ne “Directory”} |
ForEach-Object {
If (Get-Content $.FullName | Select-String -Pattern $Server) {
$PathArray += $.FullName

}
}
}).totalminutes

Write-Host "$Server is located in the following paths : " -foregroundcolor magenta
$PathArray | ForEach-Object {$_}
if (!$PathArray) { Write-Host “Server does not exist in the selected path. Please search in other locations. `n” -foregroundcolor Red }
#write-host $PathArray
#write-host "`n Time taken to search is : $time minutes. " -foregroundcolor green

#Read-Host -Prompt “Press Enter to exit”

Please use the pre tags to format your code. I’d recommend breaking things up a bit, collect the files, loop thru the files, loop thru the lines in the file, if a match is found overwrite the file.

$server = 'Server123'
$path = 'C:\Scripts'
$files = Get-ChildItem $Path -recurse -Filter "*.txt" -File | 
         Where-Object {$_.Name -notmatch "backup","Notes","test","copy"}


foreach ( $file in $files ) {

    $content = Get-Content $file.FullName
    $match = $false


    $newContent = foreach ( $row in $content ) {
        If ($row | Select-String -Pattern $Server) {
            Write-Host ('Match found for {0} in file {1}' -f $server, $file.FullName)
            $match = $true
        }
        else {
            $row
        }
    }


    if ( $match ) {
        Write-Host ('Before: {0}{0}{1}' -f [environment]::NewLine,($content -join [environment]::NewLine))
        
        Write-Host ('{0}{0}After: {0}{0}{1}' -f [environment]::NewLine,($newContent -join [environment]::NewLine))

        #$newContent | Out-File -FilePath $file.FullName -Force
    }

}

Then I can check the files are filtering:

PS C:\Users\rasim> $files


    Directory: C:\Scripts

and then I can test the match and what my newContent would be:

Match found for Server123 in file C:\Scripts\Temp0.txt
Before: 

Server1
Server2
Server3
Server123
Server153


After: 

Server1
Server2
Server3
Server153
