Thanks alot Buddy,
And yea I will try to convert it in mmap..
Ur code helped alot. But I have few doubts
1. What is the use of overlap.
2. Ur code does not end..Like it does break even after searching through the
entire file.
Bdw, I modified your code..
import os
import re
filename="E:/bitdefender/test.vmem"
read_data=2**24
offset=0
chunk_start=0
searchtext=b"bd:mongo:"
search_length=len(searchtext)
overlap_length = search_length - 1
he=searchtext.encode('hex')
with open(filename, 'rb') as f:
while True:
data= f.read(read_data)
if not data:
break
while True:
offset=data.find(searchtext,offset)
# print offset
if offset < 0:
break
print "Found at",hex(chunk_start+offset)
offset+=search_length
chunk_start += len(data)
data=data[read_data:]
offset=0
