or rather:
#!/usr/bin/env python
import string
def isbin(filename):
fd=open(filename,'rb')
for b in fd.read():
if not b in string.printable and b not in string.whitespace:
fd.close()
return True
fd.close()
return False
for f in ['/bin/bash', '/etc/passwd']:
print "%s is binary: " %f, isbin(f)
whatever... basically it's what everyone else said, every file is
binary so it all depends on your definitiion of binary.
