Could somebody help me to write a script in Powershell to
create 50 .txt files with date and the name of the file in every file?
And then rename them and add the new name and date to the second line?

IMO you are a bit stressing the goodwill of people answering,

and not any upvote yet.

## Q:Test20181119SO_53381881.ps1

$DestPath = $ENV:TMP

1..50 | ForEach-Object {

    $Now = [datetime]::Now

    $NewName = "{0}{1:00}.txt" -f $DestPath,$_

    New-Item -Path $NewName -ItemType 'File' -Force -Value "$NewName $Now`n" |Out-Null

}



## output current content

gci $Env:TMP[0-9][0-9].txt |sort name| gc





## rename by getting current numbers with a regex and subtracting 1

Get-ChildItem $Env:TMP[0-9][0-9].txt |sort name|

  Where-Object BaseName -match "^(?<Number>d{2})$"| ForEach-Object {

    $NewName = "{0}{1:00}{2}" -f $_.DirectoryName,([int]$Matches.Number -1),$_.Extension

    $_ | Rename-Item -NewName $NewName

    Add-Content -Path $NewName -Value "$NewName $Now`n"

  }

## output new current content

gci $Env:TMP[0-9][0-9].txt | gc

One liner:

1..50 | ForEach-Object {New-Item  -Path "C:temp$($_.ToString("00"))_$(Get-Date -Format 'yy-mm-dd').txt"} 

or if you want to write stuff to the file, and have something more readable

foreach ($N in 1..50){

    $FilePath = "C:temp"

    $FileName = "Text_$($N.ToString("00")).txt"

    New-Item -Path "$FilePath$FileName"

    $Date = Get-Date 

    Add-Content -Path "$FilePath$FileName" -Value $FileName

    Add-Content -Path "$FilePath$FileName" -Value $Date.ToString("hh:mm:ss dd/MM/yy")

}

note you will want to fiddle with the $Date.ToString() bit to allow for reigonal diferences.

here's an alternate method. it breaks out most of the $Vars as individual items to make the process a tad more clear ... [grin]

$DestDir = $env:TEMP

$FNamePrefix = 'Text_'

$FNameExt = '.txt'



# if you want the file content to be all on one line, remove this $Var from the "Set-Content" line

$NewLine = [environment]::NewLine



$FileCount = 5

foreach ($Count in 1..$FileCount)

    {

    $TimeStamp = Get-Date -Format 'yyyy-MM-dd HH:mm:ss'

    # create a left-padded 2 digit number string

    $Number = '{0:D2}' -f $Count

    $FileName = -join ($FNamePrefix, $Number, $FNameExt)

    $FullFileName = Join-Path -Path $DestDir -ChildPath $FileName



    # this will create the file or overwrite any pre-existing one

    #    the "-Value" stuff will be in the file

    #    to put the info all on one line use the following for the "-Value" info

    #    ""$TimeStamp; $FileName"

    Set-Content -LiteralPath $FullFileName -Value "$TimeStamp$NewLine$FileName" -Force

    }

there is no on-screen output. the content of the 1st file is ...

Text_01.txt

the name of that file is Text_01.txt. [grin]
