Read the last line of a .txt file

[ExElNeT]

I am trying to read the last line of a .txt file everytime a new line gets inserted by another program in the .txt file.

I ve tried this:

#include <File.au3>

$file = FileOpen("test.txt", 0)

; Check if file opened for reading OK
If $file = -1 Then
    MsgBox(0, "Error", "Unable to open file.")
    Exit
EndIf

        $lineCount = _FileCountLines("test.txt")
        $line = FileReadLine($file, $lineCount)
        If @error = -1 Then ExitLoop; end of file
        If @error = 1 Then
            MsgBox(0,"error","Cannot read line")
        EndIf       
        MsgBox(0,"LineCount", $lineCount & ' ' & $line)
FileClose($file)

But the output is wrong. The output line is not the last line in the .txt file

thanks in advance

I have messed with the line count command. Does not work most of the time. It is supposed to work for server logs from what I have heard.

good luck

the line number is correct. but the output doesnt match that.

$aSplit = StringSplit(StringStripCR(FileRead('FileLocation.Name')), @LF)
MsgBox(64, 'Last Line', $aSplit[$aSplit[0]])

Hi,

or, if you do not want to read a huge file and want quicker, try my "tailRW.au3" [link in signature] or wrap tail.exe.

Best, Randall
