You’re entering Serious Power territory, where it’s theoretically possible to delete a whole directory with a single typo. As a precaution, consider working through this section with administrator privileges turned off for your account (Figure 12-2), so that you won’t be able to change anything outside your home directory—or to be really safe, create a new, test account just for this exercise so even your personal files won’t be at risk.
Using the Unix command cp, you can copy and rename a file in one move. (Try that in the Finder!)
The basic command goes like this: cp path1 path2, where the path placeholders represent the original file and the copy, respectively.

The point is that you wind up with two identical files in the same directory with different names. Just remember to add a backslash before a space if you want to name the copy with two words (Thesis\ Backup, for example).
If this command doesn’t seem to work, remember that you must type the ...
