9.13. Context-Dependent Path Names

Context-Dependent Path Names (CDPNs) allow symbolic links to be created that point to variable
destination files or directories. The variables are resolved to real files or directories each time an
application follows the link. The resolved value of the link depends on the node or user following the
link.
CDPN variables can be used in any path name, not just with symbolic links. However, the CDPN
variable name cannot be combined with other characters to form an actual directory or file name. The
CDPN variable must be used alone as one segment of a complete path.

9.13.1. Usage

For a Normal Symbolic Link
ln Target LinkName
-s
Target
Specifies an existing file or directory on a file system.
LinkName
Specifies a name to represent the real file or directory on the other end of the link.
For a Variable Symbolic Link
ln Variable LinkName
-s
Variable
Specifies a special reserved name from a list of values (refer to Table 9-5) to represent one of
multiple existing files or directories. This string is not the name of an actual file or directory
itself. (The real files or directories must be created in a separate step using names that correlate
with the type of variable used.)
