Global $i = 0
$handleA = FileOpen("filea.txt",1)
$handleB = FileOpen("fileb.txt",1)
If FileRead($handleA) <> FileRead($handleB) Then
   While 1
     $i += 1
     $line1 = FileReadLine ( $handleA, $i )
     If @error Then
       MsgBox(0,"","EoF")
       ExitLoop
     EndIf
     $line2 = FileReadLine( $handleB, $i)
     If $line1 = $line2 Then 
      ;delete the line - I have no idea how :)
     EndIf
   WEnd
EndIf

Global $i = 0
$handleA = FileOpen("filea.txt",2); erase previous content, instead of deleting the differing lines, copy the matching lines
$handleB = FileOpen("fileb.txt",0)
If FileRead($handleA) <> FileRead($handleB) Then
   While 1
     $line1 = FileReadLine ( $handleA); This improves the performance (see help file)
     If @error Then
       MsgBox(0,"","EoF")
       ExitLoop
     EndIf
     $line2 = FileReadLine( $handleB); This assumes that both files has the text on the same line
     If $line1 = $line2 Then 
       FileWriteLine($handleA, $line1)
     EndIf
   WEnd
EndIf

The quoted script is somewhat adapted; thanks for the start i542.

It does not delete the lines in the first file, but writes the lines whenever these are the same in the second file.
