Hi!
I need a method like diff --brief which tells my
wether two files differ.
I looked at filecmp.cmp(), but this does not seem
to do what I want.
I did it like this, but I would prefere to use a function
from the library (if there is such a function)
def diff(file1, file2):
"""
returns 1 if the content of both files are different
returns 0 if all bytes are equal.
"""
fd1=open(file1)
fd2=open(file2)
while 1:
chunk1=fd1.read(1024)
chunk2=fd2.read(1024)
if not chunk1:
if chunk2:
return 1
else:
break
if chunk1!=chunk2:
return 1
return 0
