Purpose
Produces a list of module and driver names.
Syntax
Description
The scls command provides a method for the user to query the current Portable Streams Environment (PSE) configuration. The scls command produces a list of module and driver names. Flags can be used to produce enhanced lists. Any further parameters on the command line are module or driver names, and the output produced is for only those names.
Note: The scls command requires the sc STREAMS module and the nuls driver. If either one is not available, the scls command will not be successful.
