If you are using some type of \*nix system, the simplest way to get the last 100 lines of a log file in reverse order (that I have used) is this command:

`tac /path/to/file.log | head -100`

The `tac` command (`cat` backwards) outputs the lines of the file in reverse order -- then the `head` command returns only the first N lines. If you can put that command into an `exec` node, then the output could be send to a `ui_template` node for rendering.
