## NAME
       showmount - show mount information for an NFS server

## SYNOPSIS
### showmount  [ -adehv ]  [ --all ]  [ --directories ]  [ --exports ]  [ --help ]  [ --version ]
### [ host ]

## DESCRIPTION
       **showmount** queries the mount daemon on a remote host for information about the  state  of  the
       NFS  server  on  that  machine.   With  no options **showmount** lists the set of clients who are
       mounting from that host.  The output from **showmount** is designed to appear as though  it  were
       processed through ``sort -u''.

## OPTIONS
### -a --all
              List  both the client hostname or IP address and mounted directory in host:dir format.
              This info should not be considered reliable. See the notes on rmtab in [**rpc.mountd**(8)](https://www.chedong.com/phpMan.php/man/rpc.mountd/8/markdown).

### -d --directories
              List only the directories mounted by some client.

### -e --exports
              Show the NFS server's export list.

### -h --help
              Provide a short help summary.

### -v --version
              Report the current version number of the program.

### --no-headers
              Suppress the descriptive headings from the output.

## BUGS
       The completeness and accuracy of the information that **showmount** displays varies according  to
       the NFS server's implementation.

       Because  **showmount**  sorts and uniqs the output, it is impossible to determine from the output
       whether a client is mounting the same directory more than once.

       **showmount** works by contacting the server's MNT service directly. NFSv4-only servers  have  no
       need  to  advertise their exported root filehandles via this method, and may not expose their
       MNT service to clients.
