With no options showmount lists the set of clients who are\nmounting from that host. The output from showmount is designed to appear as though it were\nprocessed through ``sort -u''.\n\n## TLDR\n\n> Display mount information for an NFS server.\n\n- Show clients currently mounting from the server:\n `showmount {{hostname}}`\n- Show the NFS server's export list:\n `showmount {{-e|--exports}} {{hostname}}`\n- Show all clients and their mounted directories:\n `showmount {{-a|--all}} {{hostname}}`\n- Show only the directories mounted by clients:\n `showmount {{-d|--directories}} {{hostname}}`\n- Show the export list without headers:\n `showmount {{-e|--exports}} --no-headers {{hostname}}`\n- Display help:\n `showmount {{-h|--help}}`\n\n*Source: tldr-pages*\n\n## Sections\n\n- **NAME**\n- **SYNOPSIS** (2 subsections)\n- **DESCRIPTION**\n- **OPTIONS** (6 subsections)\n- **SEE ALSO**\n- **BUGS**\n- **AUTHOR**\n\nUse structuredContent.sections for detailed options, examples, and full documentation.\n" } ], "structuredContent": { "command": "showmount", "section": "", "mode": "man", "summary": "showmount - show mount information for an NFS server", "synopsis": "", "tldr_summary": "Display mount information for an NFS server.", "tldr_examples": [ { "description": "Show clients currently mounting from the server", "command": "showmount {{hostname}}" }, { "description": "Show the NFS server's export list", "command": "showmount {{-e|--exports}} {{hostname}}" }, { "description": "Show all clients and their mounted directories", "command": "showmount {{-a|--all}} {{hostname}}" }, { "description": "Show only the directories mounted by clients", "command": "showmount {{-d|--directories}} {{hostname}}" }, { "description": "Show the export list without headers", "command": "showmount {{-e|--exports}} --no-headers {{hostname}}" }, { "description": "Display help", "command": "showmount {{-h|--help}}" } ], "tldr_source": "official", "flags": [ { "flag": "-a", "long": "--all", "arg": null, "description": "List both the client hostname or IP address and mounted directory in host:dir format.
