NAME
lsvfs - list installed virtual file systems
SYNOPSIS
lsvfs [vfsname ...]
DESCRIPTION
The lsvfs command lists information about the currently loaded virtual

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) and the -t option to mount(8)
Num the filesystem type number.
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 `ufs' and devfs(5) filesystems and check the
number of mounts for the former:
$ lsvfs ufs devfs
Filesystem Num Refs Flags
