If it was a one-off I would probably use Notepad++ to do that for me rather than writing a script

Show your batch file code ... so far.

1 solution

Using PowerShell:
$files = Get-ChildItem -path C:\Data\ -filter *.txt
foreach ($file in $files)
    $content = Get-Content $file
    if ($content -match "99999999")
        $content = $content -replace "99999999", $file.BaseName
        Set-Content $file $content

Hi richard thank you so much for your response. when i try to run powershell script. I am getting the below error
Get-Content : Cannot find path 'C:\Windows\system32\70002000.LDR' because it does not exist.

we are not mapping to the path where files are existing. we are mapping to system folder. please help me

I thought you were looking at files in C:\Data\?

If you're looking at files in C:\Windows\System32\, you'll need to make sure you're running PowerShell elevated.

Also, if you've changed the Get-ChildItem call to return hidden files by using the -Force parameter, you'll probably need to pass the -Force parameter to the Get-Content call as well.

Sorry for the confusion Richard. I have din't went to the path in powershell prompt. now i checked in the way you suggested. It worked like a champ. Thank you so much for you help

one more small doubt like after fetching the value 9999999 from the file and if i want to increment the value with 1 (eg: 10000000,10000001,10000001...till files in the folders end) and replace it with incremented value instead of copying file name and replacing.

$i = 10000000
foreach ($file in $files)
    $content = Get-Content $file
    if ($content -match "99999999")
        $content = $content -replace "99999999", $i++
        Set-Content $file $content

@Richard Deeming OK, I opened Windows Power shell as an admin, should I put all the code I found above at with a space for each next line (and everything together)? I want to replace a string (or add matter just after the string) with the file name of each file for multiple files in a folder. Please answer.
