Binary on stdout

[clinux]

Hello,

I was trying to output binary in console and i noticed that many characters as well as line breaks are "executed" thus i can't view them.
However i can write binary to a file and run it.

I found a topic where people say that mode 'b' under linux is being ignored whereas under windows it's not.
So is there any workaround?

Thanks

How are you doing this (language, functions, etc.)?

If it's in C (if my guess is right), you should use fwrite(), not fprintf().

I think you'd better explain what exactly you're trying to do. I'm having a hard time understanding what someone would accomplish by writing binary data to a text console.

I'm trying it with Python

#! /usr/bin/env python
import sys

FILE = open('IMAGE.png', 'rb')
sys.stdout.write(FILE.read())
FILE.close()

sys.exit(0)

How about piping the stdout to hexdump? Not sure exactly how to do that in Python, but trying piping it to "hexdump -C" for example.

How do you expect to "view" a line break? A line break is a line break...

Actually you can "view" a line break if you look at the file in a hex editor; the line break is "0A" in hexadecimal. Thus hexdump would also work. :)

Yup, but using write() will just output the characters, not their hex values, thus a line break will be a line break. It would be nice if the OP explained a bit what he's trying to achieve.

ok i found this (http://mail.python.org/pipermail/python-list/2000-July/042460.html) post which is pretty much what i'm trying to do but it's no longer a problem :).
thanks for the replies
