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.
Usage
For a Normal Symbolic Link
ln -s TargetLinkName
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.
