New submission from Sworddragon: On reading the output of an application (for example "apt-get download firefox") that dynamically changes a line (possibly with the terminal control character \r) I have noticed that read(1) does not read the output until it has finished with a newline. This happens even with disabled buffering. In the attachments is a testcase for this problem. Also here are 2 screenshots to compare the results:
