 =====  Filenames  =====
-The rules for valid filenames vary with the filesystem, but generally, filenames may include letters, numbers, dashes, underscores, and periods. Other punctuation marks may be acceptable in some filesystems but not in others, and are therefore best avoided, especially if files may be transferred between different types of filesystems or between computers.

 Spaces may be included in filenames, but may require quoting if accessed from the command-line, so that the shell does not interpret the filename as two or more separate filenames. For example, the filename "red leaf" may be interpreted as two separate filenames if written without quoting:

 =====  Pathnames  =====
@@ Line 180: / Line 180: @@
 Relative pathnames are often the shortest form of pathname //if// the target file is in the current working directory or a subdirectory of the current working directory, but the meaning of a relative pathname changes based on the current working directory.
+===== Directory vs File Names =====
+It is often impossible to tell whether a pathname refers to a file or to a directory. For example, the Linux pathname ''/home/chris/presentation'' might refer to a file named ''presentation'' or to a directory named ''presentation''.
+If you wish to explicitly indicate that a pathname refers to a directory, append a slash or backslash to the pathname.
