tail -f c:\file.log" | sed -n -e "/error/p" -not working

Fri Jan 5 17:16:00 GMT 2001

I have duplicated this problem, using bash as the shell and a log file in the current directory (eliminating possible issues with the c:\ dos path). I also ran the test on
a Solaris system. It worked there as expected. With cygwin, it looks like the pipe is running in a buffered mode, because when I killed the 'tail...', I got the expected
output (lines containing the word 'error').
I'm not a developer in the Cygwin project and do not have any ideas about how to make this work. You might find additional information in the FAQ.
