Join Kevin Skoglund for an in-depth discussion in this video Clipboard integration, part of Unix for Mac OS X Users.
On the Mac you're probably with the concept of the Clipboard.…You're inside a document in one application, you select some text, you copy it,…you switch to another document or another application, and you paste it there.…Well, in Unix we don't have a global clipboard like that.…But we can make use of the same one that the Mac Finder uses.…And we can use it within Unix or we can use it to ferry data back and forth…between Unix and the Finder.…To do it we'll use a pair of Mac-only Unix commands called pbcopy and pbpaste.…The pb stands for Pasteboard.…Now when you're going to select something and copy it in the Finder, you use…your mouse to select it.…
But in Unix we don't have a mouse.…I mean of course I have the mouse here.…That's the Mac OS allowing me to work with Terminal.…But in Unix itself, it's all command line.…So in order to select something we're going to need to have input.…And we've already seen how to work with input in Unix.…So let's say for example that I hit ls -lah.…If I just hit Return, that'll go to standard out.…

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.
