Question
Anybody in the know of a viewer (or Notepad++ plugin) that can read txt files in a streaming way? I would like to see for example the last 10 lines of a txt file that gets appended continiously.
Solution
Tail for Win32 is a simple open-source program I've been using for a couple of years already.
Notepad++ can actually do it out of the box.
From within Notepad++: Settings > Preferences > MISC.
From there, you can check "Update silently" and "Scroll to the last line after update" in the group "File Status Auto-Detection"
Solution
The Notepad++ plugin you're looking for is Document Monitor. However, if you notice that Notepad++ freezes unpredictably, causing you to lose unsaved changes, then this plugin may be the culprit, as it is known to be unstable. See http://www.g-loaded.eu/2009/10/17/be-cautious-with-notepad/
