You can use showmount to display mounted directories.
The showmount command-line utility displays information about mounted file systems exported by Server for NFS on the computer specified by Server. If Server is not provided, showmount displays information about the computer on which the showmount command is run.
You must provide one of the following options:
- Displays all file systems exported on the server.
- Displays all Network File System (NFS) clients and the directories on the server each has mounted.
- Displays all directories on the server that are currently mounted by NFS clients.
