Powershell: Find a replace from a variable

Question

I'm new in Powershell, my code doesn't work, I can't figure out why despite spending hours trying..

What I would like to do: 1) Ask for user to type an IP Address 2) Find and replace a text by this IP Address

My variables

$demande_server = Read-Host "IP Address" >> c:\temp\SQLtemp.txt

$address = Get-Content -Path "c:\temp\SQLtemp.txt"

Then

(Get-Content -path c:\temp\SQL.txt) | foreach {$_ -replace("NomServeur=","NomServeur="$address")} >> c:\temp\SQL.txt

Thank you for your help :)

there a lot of errors. Syntactically also and by logic also. You are not at all setting the content back actually. Doing input redirection wont help there. — Ranadip Dutta

Try this logic:

$IPAddress=Read-Host "Enter the IP Address: "
$file_Content= Get-Content "c:\temp\SQLtemp.txt"
foreach($file in $file_Content)
{
$file.replace("NomServeur=","NomServeur=$IPAddress") >> c:\temp\new_OUTPUT.txt
}

So, "new_OUTPUT.txt" will have the new output which should have the replaced text.

Note: If you want to set it back to the old file. Then store the entire result in a variable and then overwrite the old file with the entire result set.

Hope it helps.

Sample OUTPUT:

This is my file content:

This is the Replaced File Content:

My Input was 192.168.1.1
