root-tail
Displays a given file anywhere on your X11 root window, i.e. it is kind of tail -f for multiple files using your desktop background as output window.
All non-option arguments on the comamnd line are files to be logged. A null desc (example: "/var/log/messages,red,") will prevent the printing of a description and the []'s.
This version of root-tail contains some enhancements I made a long time ago. It is based on a version of root-tail from ages past. In other words, you are probably better of looking here for an updated version.
This page is only still here because... well, i don't know either.
