I have a set of big (>1Gb) binary files which was uploaded to FTP with incorrect line-ending. They contain "0D 0A" where should be "0D". Is there a way in Linux to replace all includings of bytes "0D 0A" to "0D" in command line?

  • @J.F.Sebastian There is a difference between removing bytes and replacing, I would like to replace, not delete. And it is impossible to install non-standard utilities. Only sed, bash, tr is available... Commented Dec 16, 2013 at 1:38

    I don't understand your comment e.g., in what way sed $'s/\r$//' fails for you? There could be invalid for your use-case answers but the question is 100% related. Commented Dec 16, 2013 at 1:45

    I've noticed that instead of replacing \r\n with \n, you want replace \r\n with \r. Is it correct? Commented Dec 16, 2013 at 1:58
  • @J.F.Sebastian Yes, I wrote about I need for \r, but actually I am looking for relatively universal solution for replacement bytes. I've tried everything already and didn't get any positive result. But thanks, your comment would be best answer. Commented Dec 16, 2013 at 6:11

You can use the command dos2unix. The inverse is unix2dos, of course.
