App with tail Command? Is there an app that will let me run the UNIX tail command?

I want to be able to monitor a text file on a remote web server as it gets written to.
I don't know the syntax, but Terminal Emulator on my Samsung Galaxy S lets me run tail.  I would assume any console app would allow it.

As noted in the comments below, tail is part of BusyBox so you can get it from there.  There is a root app on the Play Store  that includes BusyBox if you don't want to search for a package to sideload.
