Binary grep on Linux?

Question

Say I have generated the following binary file:

# generate file:
python -c \'import sys;[sys.stdout.write(chr(i)) for i in (0,0,0,0,2,4,6,8,0,1,3,0,5,20)]\'          


        

Answer 1

Someone else appears to have been similarly frustrated and wrote their own tool to do it (or at least something similar): bgrep.
