 #### Unix/Linux Pathnames
 
-Filenames and pathnames on Unix-like systems are not always easy to deal with either. On most Unix-like systems, a filename can be any sequence of bytes that does not include **\0** (the terminator) or slash. One common misconception is that Unix filenames are a string of characters. Unix filenames are not a string of one or more characters; they are merely a sequence of bytes, so a filename does not need to be a legal sequence of characters. For example, while it is a common convention to interpret filenames as a UTF-8 encoding of characters, most systems do not actually enforce this. Indeed, they tend to enforce nothing, so many problematic filenames can be created, including filenames with spaces (or only spaces), control characters (including newline, tab, escape, etc.), bytes that are not legal UTF-8, or

 Some potential problems with filenames are specific to the shell, but filename problems are not limited to the shell. A common problem is that “**-**” is the option flag for many commands, but it is a legal beginning of a filename.
