Join Kevin Skoglund for an in-depth discussion in this video System configurations: Examples, part of Unix for Mac OS X Users.
In this movie, I want to show you a few of the most popular system…configuration changes.…The first one will show all the dot files in the Finder.…Remember that by default the Finder hides all our dot files so that we can't see them, …but we could change that behavior. If we want to make them visible we'd…say defaults write com.apple. Finder and then ShowAllFiles true.…If you ever decide you want to turn it off again, ShowAllFiles false.…Or if you want the Unix path to display in the Finder windows up at the top,…well its default is write com.apple. Finder, and then _FXShowPosixPathInTitle…using all the correct capitalization, and then -bool TRUE, setting a Boolean to true.…
If you wanted to go away then you'd just set it to bool False.…We can also configure some of the defaults for screen capturing. We saw a little…bit about how to trigger screen capturing from Unix.…We can change how the Mac does its screen capturing permanently even in the…Finder by setting defaults write com. apple.screen capture. Type is we can set…

Q: The exercise files for the following movies appear to be broken:<br /> 07_02_files<br /> 07_03_files<br /> 07_04_files<br /> 07_05_files<br /> 08_03_files<br /><br /> 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:<br /><br /> 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).<br /> 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.<br /> <br /> OR<br /> <br /> 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.<br /> Example: cp -i ~/Desktop/Exercise\ Files/Chapter_07/07_02_files/bashrc_example ~/.bashrc
