There is a already question that asks about opening a large log files.

But my intention is different. Is there any application that monitors a log file and updates as it is updated in real time?

Platform: Windows XP/2003/2008 server

[Update] this is quite handy for a quick monitoring(thanks to Ckarras's answer)

@Sung, Do you need readonly or editable? – Pacerier Aug 25 '15 at 10:29

I've been using BareTailPro for awhile, and have been very pleased. It hasn't been updated in awhile, but it still meets my needs. There's also a free version.

Here's some of the features:

  • View files of any size (> 2GB)
  • Configurable highlighting
  • Monitor multiple files simultaneously
  • High-performance search algorithm
  • Regular expression text search
  • Filter tail mode (include or exclude lines)

This is what (BareTail Free version) I settled with for now. Thanks Rob – Sung Jul 19 '09 at 17:35

I use Notepad++ as my default text editor on all my systems, and it has the nice bonus of having this built-in - just go Plugins -> Document Monitor -> Start to monitor. You can also use File -> Reload from disk to manually reload it.

+1 Wow, I have been using Notepad++ for awhile but didn't know about this functionality. thanks. – Sung Apr 30 '09 at 23:57
does this still exist, I don't see it in version 5.9.8 that I just downloaded. – Scott Jan 20 '12 at 17:07
@Scott can be downloaded as a plugin – Fishcake May 11 '12 at 10:18
+1 from me too. I love Notepad++ but didn't even think of looking for a plugin. Bye bye BareTail. – Fishcake May 11 '12 at 10:19

You don't mention which platform you're using, but on Unix-like systems the tail command does this:

tail -f /var/log/messages

In fact there are implementations of tail for Windows also (eg. unxutils).

share|improve this answer

If windows is your thing you could try Tail for Win32.

edit: Another alternative I just found is TailXP. It's free, but not opensource. Looks ok from the description but I haven't tried it.

share|improve this answer
The advanced features feel a little buggy but for simply tailing the file, it's perfect. – Michael Haren Apr 30 '09 at 23:10
Because of "tail" stuff people were mentioning, I found something called "BareTail" - So far it seems to be doing what I wanted. But I am open for more suggestions. – Sung Apr 30 '09 at 23:34
That one looks nice to know about too. – Jorge Alves Apr 30 '09 at 23:40

Actually, Log-Expert does what you want, plus a lot of nice feature

Features for Log-Exprt

yeah, this solution rocks. Better than notepad++, which only updates every 3 seconds, and is a bit flaky. – Jacko Mar 10 '11 at 19:52
Plus its free :) – Sameer Alibhai Apr 7 '15 at 19:15
@VonC, Any disclaimers? – Pacerier Aug 25 '15 at 10:29
@Pacerier none that I can think of. But that was 6 years ago. – VonC Aug 25 '15 at 10:33

There's also an equivalent to "tail -f" under Windows, if you have PowerShell installed:

type -wait
share|improve this answer
Wow. this is quite awesome. I had no idea about that "-wait" option for "Get-Content". Thanks ckarras. I have also updated question with the screenshot. – Sung Sep 12 '09 at 17:41
Have an upvote for giving an answer that shows you can do this right out of the box if you know how to use OS and that you don't need to install 3rd party tools. – Ryan Ries Nov 9 '12 at 13:51

Like tail -f file.log?

share|improve this answer
But doesn't this mean I have to be running the command constantly? – Sung Apr 30 '09 at 23:20
No, the tail command will wait after printing the last line, and when the file is updated/appended it will print the new line(s) and wait again. Instead of plain tail you might try – hlovdal Apr 30 '09 at 23:26
He also said for the Windows OS. – Pure.Krome May 1 '09 at 0:02
Not when I answered, he hadn't. – Ben Alpert May 1 '09 at 0:32

I have had good luck with the windows program mtail. It does a very nice job of monitoring an active log. You can configure quite a few options but in general I have found the defaults work very well.


share|improve this answer
Great! I didn't get to run into this one. – Sung May 3 '09 at 0:23

"tail -f logname"?

share|improve this answer
He edited his post to say it's for Windows OS only. – Pure.Krome May 1 '09 at 0:02
There are plenty of versions of tail for Windows, including in cygwin. – Paul Tomblin May 1 '09 at 0:13

I love the Kiwi Log Viewer. They were just bought out by Solarwinds -- I assume the product is still for sale (or maybe they're giving it away for free now? They're giving away a few other Kiwi products).

share|improve this answer
Would you post link to Kiwi Log Viewer? I am not sure if this one I found is the one you are referring to: – Sung May 3 '09 at 0:22
Yeah, that's the one -- – DougN May 4 '09 at 15:35

If you install Cygwin on your Windows machine, you can run tail

share|improve this answer
Hmm. Cygwin. I haven't played around with that for years... – Sung May 3 '09 at 1:49

I typically do this with TextPad. It has the option to monitor that a file has been modified. It is an option to either automatically update the window or to prompt you whether or not you want to reload the file.

share|improve this answer
It looks like TextPad has a the same capability as NotePad++'s Document Monitor plugin – Sung May 3 '09 at 0:26

If you're using eclipse there's a fully sick plugin called Log Watcher

It supports multiple files, plus color highlighting.

I know its a bit late, but as someone else mentioned, I really like Tail For Win32 - I produced a short video showing how I used it to monitor a robocopy log during a ton of files being transferred from one computer to another.

---> LINK TO VIDEO <---

share|improve this answer
It's never late, but it sometimes is a duplicate - there is already an answer pointing to tailforwin32. You might choose to link to your video in a comment there and delete this answer. – the-wabbit Jan 25 '12 at 13:23
