From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bob McGowan To: Nush Pera Cc: Cygwin Subject: Re: tail -f c:\file.log" | sed -n -e "/error/p" -not working Date: Fri, 05 Jan 2001 17:16:00 -0000 Message-id: <3A5672E7.8D4B37C3@veritas.com> References: <20010105093103.8551.qmail@nw175.netaddress.usa.net> X-SW-Source: 2001-01/msg00210.html 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.
