tail -f problem
All, This is my first post to this list, so please excuse missing information that is normally seen in a possible problem with cygwin. Here goes... In my career, I'm a software consultant, doing QA on a web client/server application. Part of my investigation of issues is looking at the realtime log files of our web server (IIS in this instance). Under linux, tail -f, across a smbmount will perform exactly what I need to parse and view the log files as activity happens (I also use a cut to kill a few fields that aren't needed). Problem is, my main machine isn't linux and there isn't another linux machine around here for me to do this with (the only linux machine is a mail server which does not have a route to the areas I need to view). With cygwin's tail, the output is not quite the same as the linux version of tail. With Cygwin's version, I will get output with tail -f, but the updates aren't realtime as the linux version -- the updates are barely shown at all, if ever. Here are the different methods I used to try and parse the IIS log file: 1. Map the share of the logfile with my Windows XP machine to say Z:, etc, use cygwin.bat to launch a bash.exe shell, go to the logfile directory and tail -f name.log. 2. Terminal Service to the machine, go cmd.exe (with cygwin in the path), CD to the logfile folder and tail -f name.log. 3. Use cygwin.bat to invoke bash.exe, go to my local logfile folder and tail -f the contents of name.log. Either of these ways to access the logfile will give me the first 5 (or X lines, using the -n option) lines, then pretty much stop outputting, or slow the outputs to a virtual crawl. I must CTRL-C to break out the tail, and start it over to get the output starting again. I've tried using the -s, to sleep tail and have it try again, but this did not increase the output at all. Here are more version #s and machine info: My workstation: Dell laptop, Windows XP (non SP1 My servers: Dell rackmount, Windows 2000/SP2, IIS. Cygwin version: 1.3.19-1 Tail version: February 19, 2002, 3:26:34 PM I am very willing to answer questions anyone has, because I would like to know if anyone else has the same problem.

RE: tail -f problem
I've read the archives (now that I found it) about other people posting about this. However, this does not change the fact that linux's version of tail works plenty fine with viewing IIS logfiles vs. Cygwin's version of tail. -Original Message- From: Matthew Smith [mailto:[EMAIL PROTECTED]] Sent: Friday, January 31, 2003 10:39 AM To: Cygwin Cc: Scott Alexander Subject: Re: tail -f problem This is not the fault of tail, rather IIS.

Re: tail -f problem
This is not a simple issue of the linux tail works, and the cygwin tail doesn't. You're exporting an smb share, which most likely (or could possibly) affect buffering/flushing. At any rate, if the linux tail is working for you, use it. cheers, -Matt I've read the archives (now that I found it) about other people posting about this.
