Shell Scripts

The title of my post will be Shell Scripts, yet again. I am still learning the unix commands and how to put them together. It should be simple to write a script to systimatically go through all the wograld directories and delete the Makefile and Makefile.in that do not need to be there. I'm pretty sure now that it is only supposed to be Makefile.am in each directory. This is something I did not realize before. Also, I need to write a script that goes through every file and then replaces every instance of crossfire with wograld. I know that one is probably going to be a pain. How am I going to like it when every file asks me if it is okay to overwrite it. On the other hand, I do not see how else to do a true fork of the project, and I do not think doing every single line by hand would be less tedious, it would probably be more tedious. Even if I have to confirm every instance of mv, it would still be faster than replacing every instance of crossfire in every file with wograld by hand.
I would not be surprised though if I never figure it out or if it is 100 years before the shell script gets written. It just seems like something that is too complex for any mortal being to do. Ironically, neither of the other team members are capable of doing it even though both of them made a living in computers and programming. Shell scripters are probably pretty rare and value able.
