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
-s
Target LinkName
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
-s
