Many of the interfaces described in the X/Open Commands and Utilities Specification (see reference XCU) are directly or indirectly concerned with accessing files stored on the system's file system. This appendix identifies those commands and utilities which may operate differently when used with XNFS.
The table "Utilities with no Semantic Differences" below lists the commands and utilities that show no semantic difference when invoked in an XNFS environment. That is, they behave the same as when running in a local file system environment.
The following utilities and commands have no change over XNFS:
|Utilities with no Semantic Differences|
The following differences apply to almost all of the commands and utilities that may show semantic differences under an XNFS environment.
This applies to all of the utilities and commands. If local execution of a remote utility or command occurs (such as executing the remote image of cmp locally), then the following semantic difference applies:
All NFS operations involve issuing one or more requests from the client to the server. Therefore the following semantic difference applies to all NFS operations:
Every command or utility that opens and then accesses a remote file is subject to the following semantic differences:
Remote file access could conceivably occur with every command or utility if its standard input or standard output is redirected to a remote file.
The following is a list of those utilities and commands that have semantic differences:

Where the semantic difference described only applies to the XNFS Issue 3W Specification this is identified by shading of the appropriate text. Semantic differences which do not contain this code marking are applicable to both XNFS Issue 3 and XNFS Issue 3W Specifications.
