I don't really know what exactly you're trying to accomplish, a little more info would help, but you just stated you want to compare the last three lines in a file. You can use StringCompare to do that

#include <File.au3>

Example()

Func Example()
    Local $aFile
    Local $iLastIndex
    Local $iCompare1
    Local $iCompare2
    Local $iCompare3

    _FileReadToArray(@ScriptDir & "\Test File.txt", $aFile, $FRTA_NOCOUNT)
    
    If (@Error) Then
        MsgBox("", "_FRTA Error", "Failed to read file to array")
        Return
    EndIf
    
    If (UBound($aFile) >= 3) Then
        $iLastIndex = UBound($aFile) - 1
        $iCompare1 = StringCompare($aFile[$iLastIndex], $aFile[$iLastIndex - 1])
        $iCompare2 = StringCompare($aFile[$iLastIndex - 1], $aFile[$iLastIndex - 2])
        $iCompare3 = StringCompare($aFile[$iLastIndex - 2], $aFile[$iLastIndex])

        MsgBox("", "Compare", "Last line and one line before last: " & ($iCompare1 = 0 ? "Equal" : $iCompare1 > 0 ? "Last line is greater" : "Line before last is greater") & @CRLF & _
                                "One line before last and two lines before last: " & ($iCompare2 = 0 ? "Equal" : $iCompare2 > 0 ? "Line before last is greater" : "Two lines before last is greater") & @CRLF & _
                                "Two lines before last and Last line: " & ($iCompare3 = 0 ? "Equal" : $iCompare3 > 0 ? "Two lines before last is greater" : "Last line is greater"))
    Else
        MsgBox("", "Array Size", "Array is too small to compare")
    EndIf
    
EndFunc

hi thanks for your reply i got a text file filled with numbers in one column like

 

2

3

4

5

5

5

I want when i find 3 instances like 5,5,5 to throw an error but always the last line compared to the x2 above ones thanks

If they're just numbers then you don't need to do StringCompare.

Sounds like you're just trying to make sure that there isn't three consecutive lines with 5s on them?

#include <File.au3>

Example()

Func Example()
    Local $aFile
    Local $bError = False

    _FileReadToArray(@ScriptDir & "\Test File.txt", $aFile, $FRTA_NOCOUNT)

    If (@Error) Then
        MsgBox("", "_FRTA Error", "Failed to read file to array")
        Return
    EndIf

    For $i = UBound($aFile) - 1 To 2 Step -1
        If ($aFile[$i] = 5 and $aFile[$i - 1] = 5 and $aFile[$i - 2] = 5) Then
            $bError = True
            ConsoleWrite("Detected three 5s on lines " & ($i - 1) & " to " & ($i + 1) & @LF)
        EndIf
    Next

    If ($bError) Then
        MsgBox("", "555", "Error detected in file")
    Else
        MsgBox("", "No Errors", "No errors detected in file")
    EndIf
EndFunc

Idk why I did it backwards through the file but that's how I did it.... lol

8 => $STR_STRIPALL and 0 => $MB_OK

You can try this

$txt = StringStripWS(FileRead("1.txt"), 8)
If StringRegExp($txt, '(.)\1\1$') Then Msgbox(0,"", "the 3 last ones are the same")

 

thank you so much everybody for your replies the above example is very nice and small 2 lines only

any way on top of that to also detect if there is the number 4 present before the 3 that we are already comparing  ? cheers
