Join Kevin Skoglund for an in-depth discussion in this video Copying files and directories, part of Unix for Mac OS X Users.
Now, I would like to talk about how to copy them.…Let's take a look. First of all, we'll do ls -la.…Notice that I'm inside my unix_files directory now, which is inside my user root.…At the end of the last movie we moved everything into this folder.…So you can see I have got all of my unix_files just in this folder.…Now, I'll start by doing cat new_file.txt.…It's just a very simple text file.…Let's copy that. We use cp to copy and we start by saying copy these source.…
Our source for this is going to be file.txt.…Again, we can provide a full path to that source.…It doesn't have to be something that's in this current directory.…It can be an absolute path or a relative path. And then the destination, the target.…And again, absolute or relative path.…In this case, we are going to call it newer_file.txt. It did it.…Say ls -la,. We can now see the newer file there and cat newer_file and we see…that it copied the content as well. So it's that easy.…
It really is just using the cp command to do a copy.…

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
