LSVFS(1)		FreeBSD	General	Commands Manual		      LSVFS(1)

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 in-
     formation 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 pa-
		 rameter 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
	   -------------------------------- ---------- -----  ---------------
	   ufs				    0x00000035	   2
	   devfs			    0x00000071	   1  synthetic, jail

	   $ mount -t ufs | wc -l
		  2
