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

[Bob McGowan <rmcgowan at veritas dot com>]

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.
