Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Given thaqt directories are just special files, I suppose you could just edit them with debugfs or the like, however this is a really bad idea in all but the most desperate of circumstances (e.g. trying to recover a seriously hosed filesystem), and it should never, ever be done on a mounted filesystem.
Like pixellany asked, what exactly are you trying to do that you can't use rm?

Reason: typo removal
The chosen filesystem has a big impact on this. Some filesystems are faster than others at deleting files. You can't just redirect a tree to null nor anything like that. The files need to be unlinked from the filesystem one by one, directories can't be deleted unless the only files inside them are . and ..
rm is as fast as it can be, if the file list is really really long, you can use xargs to work around it.
