13. Context-Dependent Path Names

Context-Dependent Path Names (CDPNs) allow symbolic links to be created that point to vari-

able 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.

For a Variable Symbolic Link

ln -s VariableLinkName

Variable

Specifies a special reserved name from a list of values (refer to Table 4.5, “CDPN Variable
