Simple utility to grep/find a byte pattern in a file. I can only assume you can use grep or some other utility to do this as well.

bin-grep.py

#!/usr/bin/python

from sys import argv

path = argv[1]
hex_pattern = argv[2]

str_pattern = "".join([chr(int(hex_pattern[x:x+2], 16)) for x in range(0,len(hex_pattern), 2)])

with open(path, 'r') as f:
  data = f.read()

pos = data.find(str_pattern)


if pos >= 0:
	while pos >= 0:
		start = max(0, pos - 16)
		end = min(len(data), pos + len(str_pattern) + 16)

		print "Found at position %d. Showing characters %d-%d" % (pos, start, end)
		print data[start:end]
		print "".join([" " for x in xrange(start, pos)]) + '^'

		pos = data.find(str_pattern, pos + 1)
else:
	print "Not found."
