# lsvfs(1)

list installed virtual file systems

## NAME

**lsvfs** – list installed virtual file systems

## SYNOPSIS

**lsvfs** \[*vfsname* *...*\]

## DESCRIPTION

The **lsvfs** command lists information about the currently loaded virtual file system modules. When *vfsname* arguments are given, **lsvfs** lists information about the specified VFS modules. Otherwise, **lsvfs** lists all currently loaded modules. The information is as follows:

- Filesystem

  the name of the file system, as would be used in the *type* parameter to [mount(2)](/mount/2.md) and the **-t** option to [mount(8)](/mount/8.md)

- Refs

  the number of references to this VFS; i.e., the number of currently mounted file systems of this type

- Flags

  flag bits.

## EXAMPLES

Show information about the ‘apfs’ and ‘devfs’ filesystems and check the number of mounts for the former:

```
$ lsvfs apfs devfs
Filesystem                        Refs Flags
-------------------------------- ----- ---------------
apfs                                 5 local
devfs                                1
$ mount -t apfs | wc -l
       5
```
