Case Sensitivity and Special Characters
Newcomers to Linux can sometimes run into problems, particularly if they come from a Windows background in which all three of the folders Business, business, and BUSINESS refer to the same directory. This is because Linux (like Unix) is case-sensitive when it comes to files and folders. So, to avoid confusion, you may wish to always use lowercase file and folder names, at least until you are used to this system.
Also, if you ever want easy access to your filesystem from the command line, I recommend you steer clear of using spaces in your file and folder names because you would then have to use quotation marks to surround them. Instead, try using underscore or hyphen characters.
You should also avoid using special characters such as *, ?,
>, and | in your filenames because each has a different
meaning to Ubuntu (explained in Chapter 7), and
using them will give you unexpected results.
