Join Kevin Skoglund for an in-depth discussion in this video Conclusion, part of Unix for Mac OS X Users.
I want to thank you for taking Unix for Mac OS X Users.…Over the course of this training title we've come a long way, from simply…changing directories in the command line all the way to power user techniques.…And don't worry if it takes a while for some of these commands become a routine.…Remember that you always have the man pages to remind you of the command syntax and…its available options.…I've been using Unix for 20 years and I still look up things all the time, and…those built-in man pages? They're also one of the best resources for you to…continue advancing your Unix skills.…One point that I hope you've picked up on while we we're learning is that…Unix is as much a part of your Mac as the Finder is. In fact Unix is what…makes the Finder possible.…
The Finder is a layer of convenience that sits on top of Unix.…So when you want convenience, use the Finder. When you want power, use Unix.…And when you can switch back and forth, and integrate both in your workflow then…you can work faster and get more power out of your computer.…

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
The instructor uses the UNIX program 'units' to convert 72° Fahrenheit to degrees Celsius. The returned value of 40 is incorrect. The correct result should be 22°C. What's the reason for this discrepancy?
The problem is that units does the 5/9 calculation but does not have the ability to subtract 32. So you'll need to subtract (or add) the 32 degrees yourself.
