It can also be used to reinitialize this information. If no options are given, nfsstat displays both server RPC and NFS version 2 and version 3 information, and client RPC and NFS version 2 and version 3 information. The system argument specifies the file containing the system's name list. Otherwise, /vmunix is used. FILES
