hexnumber from many files in windows.

I want to read the hexnumber in pos 29 on many files of a type (*.dat) and print it to a log + the path and filename.


What is the best method to do that in Windows?

Pretty much write a small app. Python maybe, or Java, or such since you'll need to translate the hex byte to its ASCII representation. For the adventurous, there's Cygwin, so you can use UNIX-like commands under Windows.

Hi thanks

in putfile I want to read the 05 on pos 30
66 64 73 64 46 63 76 62 66 67 56 E7 FE 74 56 1D 44 54 46 6A 4D 0A 4E 04 01 70 0F 00 00 05 00 00 00 00 00 00 00 02 00 00


I tryed in python but:

infile = "test.dat"

FH = open(infile, 'rb')
FH.seek(30,0)
FH.tell()
line = FH.read(2)


print line

FH.close()

I don't output 05

OK - what is it returning? If the file is truly a binary file, you'll need to convert the 0x05 to ASCII "0" and "5". If the file's actually the ASCII dump of the binary, location 30 isn't going to be where byte 30 is stored; it's going to be more like where byte 15 is stored since an ASCII representation of a single byte needs 2 bytes.
