Filename Exercise:

1) Copy filename_exercise.csh into your local working directory.
2) Run the script. It will produce some files with spaces in the names.
3) Write a script to replace the spaces with underscores.

Hints: 
Copy filename_exercise.csh to rename_files.csh and edit it.
These commands may help you understand how it works:
	man tcsh
	man basename
	google "csh filename with space"
If you can't figure it out, then look at answer.csh, and make sure you understand the solution.
Save your result- you will likely find it useful in the future,.
