Thank you for the report. I too see that behavior, but it is not a problem with grep. It is due to the way carriage returns are rendered. Here, even without --color, you can see that the three matched line render as empty: $ printf 'line%s\r\n' 1 2 3 | grep . However, if you pipe that result through cat -A, you see that grep is working as required: $ printf 'line%s\r\n' 1 2 3 | grep .|cat -A line1^M$ line2^M$ line3^M$ So I'm closing this bug.
