Multitail: one that is hard to live without

In the realm of utilities this one is a jewel. Multitail lets you set up colorized log following that can be done via ssh remoting as well as on the system. The newest version is absolutely killer when you build it on your cygwin and then you can point it at any number of systems.

If you have a second monitor run multitail in a big rxvt window and you can watch all the logs you'd ever want to watch.

I like multitail because you can capture the output of any program you write as a filter and multitail itself has several great filters. Its a very very useful tool. Probably one of the very best going.
