Answer 1

This is my take on it, building on some of the other answers here:

Function ReplaceTextIn-File{
  Param(
    $infile,
    $outfile,
    $find,
    $replace
  )

  if( -Not $outfile)
  {
    $outfile = $infile
  }

  $temp_out_file = "$outfile.temp"

  Get-Content $infile | Foreach-Object {$_.Replace($find, $replace)} | Set-Content $temp_out_file

  if( Test-Path $outfile)
  {
    Remove-Item $outfile
  }

  Move-Item $temp_out_file $outfile
}

And called like so:

ReplaceTextIn-File -infile "c:\input.txt" -find 'http://example.com' -replace 'http://another.example.com'
