Naming Conventions—UNIX or Linux

Use the following format to name a UNIX or Linux file:

/directory/subdirectory/.../filename

Use up to 256 characters for the entire path of the file; there are no restrictions on size for the individual parts of the path.

The following list describes the parts of a UNIX or Linux path:

/ (slash): The root directory when it is in the first position: otherwise, the slash separates directories and file names in the path.
directory: Specifies the directory that contains the file. You can specify more than one directory in a path.
filename: Specifies the name of the UNIX or Linux file.
