Creating a 'tail' type system on a webpage

[gremin]

Im wondering if anyone has any ideas on how to mimic the unix 'tail -f' command using PHP (or something) on a webpage?

You'd have to reload the page every so often using javascript (set a timeout) or a meta refresh tag.

Get the output from your command, store it in an array, and display the last N rows.

Yea - been working down that path, but i really want the data to display as the file changes and to scroll rather than reload... its very hard to read when it refreshes - thus kind of killing what the function is for in the first place... Any suggestions are welcome. A java appelt maybe?

AJAX (http://www.adaptivepath.com/publications/essays/archives/000385.php) perhaps?
