Compare file text and size


Recommended Posts

Does it have to be AutoIt or will another tool like Winmerge fit your needs too?

Use function "FileGetSize" to retrieve the size of a file.

How big are the files you need to compare?

20 kb file size .

FileGetSize will compare the file size.

But how to compare the file contents.

ex:I have a file ex: data.txt in PC location.I downloaded the same file data.txt from cloud.so i need to compare the file contents.If both file contents and size are same then pass msg as file downloaded successfully.

Something like this? Pass the two filenames to compare to the function.

; Compare FileSize and Content. Returns 1 if equal, 0 if not equal, -1 for error
Func _CompareFiles($sFile1, $sFile2)

    If FileGetSize($sFile1) <> FileGetSize($sFile2) Then Return 0
    $sFile1Content = FileRead($sFile1)
    If @error Then Return -1
    $sFile2Content = FileRead($sFile2)
    If @error Then Return -1
    If $sFile1Content <> $sFile2Content Then Return 0
    Return 1

EndFunc   ;==>_CompareFiles

Here another way to compare line by line:

#include <Array.au3>
#include <File.au3>

$aFileCompare = TextFileCompare("C:TempSilverlight0.log", "C:TempSilverlight1.log")
_ArrayDisplay($aFileCompare)

Func TextFileCompare($sFile1, $sFile2)
    If Not FileExists($sFile1) Or Not FileExists($sFile2) Then Return SetError(1, 0, 0) ;at least one file doesn't exist
    If Not FileGetSize($sFile1) Or Not FileGetSize($sFile1) Then Return SetError(2, 0, 0) ;at least one file is empty
    Local $aFile1, $aFile2, $i, $j = 1
    _FileReadToArray($sFile1, $aFile1)
    If @error Then Return SetError(3, @error, 0) ;file couldn't be read to the array
    _FileReadToArray($sFile2, $aFile2)
    If @error Then Return SetError(4, @error, 0) ;file couldn't be read to the array

    Local $aResult[Max($aFile1[0], $aFile2[0]) +2][3]
    Local $iMin = Min($aFile1[0], $aFile2[0])
    Local $bDiff = False
    For $i = 1 To $iMin
        If $aFile1[$i] <> $aFile2[$i] Then
            ConsoleWrite("Line " & $i & ": " & $aFile1[$i] & " <!> " &  $aFile2[$i] & @LF)
            $aResult[$j][0] = $i
            $aResult[$j][1] =  $aFile1[$i]
            $aResult[$j][2] =  $aFile2[$i]
            $bDiff = True
            $j += 1
        EndIf
    Next
    If $aFile1[0] > $aFile2[0]  Then
        $bDiff = True
        For $i = $aFile2[0] + 1 To $aFile1[0]
            ConsoleWrite("Line " & $i & ": " & $aFile1[$i] & " <!> " & @LF)
            $aResult[$j][0] = $i
            $aResult[$j][1] =  $aFile1[$i]
            $aResult[$j][2] =  ""
            $j += 1
        Next
    ElseIf $aFile1[0] < $aFile2[0] Then
        $bDiff = True
        For $i = $aFile1[0] + 1 To $aFile2[0]
            ConsoleWrite("Line " & $i & ":  " & " <!> " & $aFile2[$i]  & @LF)
            $aResult[$j][0] = $i
            $aResult[$j][1] =  ""
            $aResult[$j][2] =  $aFile2[$i]
            $j += 1
        Next
    EndIf
    If Not $bDiff Then
        ConsoleWrite("Files are equal!" & @LF)
        Return 0
    EndIf
    $aResult[0][0] = "Line"
    $aResult[0][1] =  $sFile1
    $aResult[0][2] =  $sFile2
    ReDim $aResult[$j][3]
    Return $aResult
EndFunc

Func Min($a, $b)
    If $a < $b Then Return $a
    Return $b
EndFunc

Func Max($a, $b)
    If $a > $b Then Return $a
    Return $b
EndFunc
