Join Kevin Skoglund for an in-depth discussion in this video Using the exercise files, part of Unix for Mac OS X Users.
If you are a premium member of the lynda.com Training Library or if you're…watching this tutorial on a disc, you'll have access to the Exercise Files that…are used throughout this title.…The Exercise Files for this title are arranged by chapter and by movie, and you…can find the Exercise Files that correspond movie that you're watching by first…looking for the chapter number and then the movie number.…You'll want to copy the contents of that folder into your user directory or to…another convenient location.…It's always a good idea to make a copy so that you still have the original to…refer back to if you make changes.…
To do this on my Mac I open up a new window using Command+N, which by default…opens in my user directory, and then I can simply Option+Drag over the folder…contents from the Exercise Files to create a copy.…Once you do that your files will be the same as mine at the start of that movie…and you'd be able to follow right along with me from there.…For some movies, the Exercise Files include one or more dot files.…

Q: The exercise files for the following movies appear to be broken:
Is there something wrong with them?
These exercises include one or more "dot files", whose file names start with a period. These files are normally hidden from view by the Finder. So that they would show up in the Finder, the period has been removed from the file names. Additionally, "_example" has been added at the end of the file name to make it clear that the file will not work as-is.
To make the dot files usable, either:
1) Open the file in a text editor to view its contents. Note that it may not be possible to double-click the file to open it because there is no file extension (such as .txt).
2) Resave the file under a new name (usually by choosing File > Save As), adding a "." to the beginning of the file name and removing "_example" from the end.
1) Copy and rename the file from the Unix command line using the techniques discussed in this course. Rename the file by adding a "." to the start and removing "_example" from the end. Include the "-i" option to prevent overwriting an existing file unexpectedly.
Example: cp -i ~/Desktop/Exercise\ Files/Chapter_07/07_02_files/bashrc_example ~/.bashrc
