Find differences between 2 text files

[myspacee]

hello to all,

try to understand how find differences between 2 attached text files:

both are create from a procedure, but sometime @LF is correct, sometime is identified as a small square.

Try _FileCountLines, stinginstr, without luck.

If you open files with notepad you can see differences, but can't script a way to find differences.

Anyone can solve this mistery?

Thank you,

m.

What do you want to do? Find the diffs and then?

I need this list to copy, move, rename lot of files.

The difference is that file A is coded with a linefeed (0x0A) and file B is coded with carriage return + linefeed (0x0D plus 0x0A) as required by windows.

Have a look at function "StringAddCR". This adds the "missing" carriage return character. If you read file A, use StringAddCr and rewrite the file then file A should be equal to file B.

Seems that it is reading the [] character as a TAB when this is generated is it using tab or @Crlf or r/n ?

Thank you all for attention,

water thank you for info, but i must decide which is A type and B type file, before act with a script.

lordicast sorry but can't understand your info request.

any other idea ?

you could use this stringregexp to get the values.

'PVV\d*P\s\w{6}\s\d*'

this will work for your posted text file..... but dont know how different (flexible) your other text files will be.

To determine the type of file just read x bytes from the file (x > longest line in file. 200 bytes in the example) and search for the carriage return character

#Include <String.au3>
$sText = FileRead("C:\TEMP\A.TXT",200)
If StringInStr($sText,_HexToString("0D")) = 0 Then
    ConsoleWrite("Carriage Return not Found" & @CRLF) 
Else
    ConsoleWrite("Carriage Return Found" & @CRLF) 
EndIf

Maybe it will be simpler to use external utils for comparing 2 files.

There are some freeware utilities for this also with commandline support:

PSPad, WinDiff, WinMerge
