 Only print out statistics for filesystems of the specified types.

-The recognized types are:
-ufs, nfs, mfs, lfs, pc, fdesc, portal and kernfs,
-along with the aggregates:
-all (the default),
-local (ufs, mfs, lfs),
-and misc (fdesc, portal, kernfs).
-The string ``no'' may be prepending to a type to get its complement
-(e.g. ``nonfs'' to get non-NFS filesystems).  The first
-.Fl t
-option overrides the default, additional such options will add to
-(or subtract from) the current set of types; e.g. either
-``df -t ufs -t lfs''
-or
-``df -t local -t nomfs''
-will display statistics for UFS and LFS filesystems.
+More than one type may be specified in a comma separated list.
+The list of filesystem types can be prefixed with
+.Dq no
+to specify the filesystem types for which action should
+.Em not
+be taken.
+For example, the
+.Nm df
+command:
+.Bd -literal -offset indent
+df -t nonfs,mfs
+.Ed
+.Pp
+lists all filesystems except those of type
+.Tn NFS
+and
+.Tn MFS .
+The
+.Xr sysctl 8
+command can be used to find out the types of filesystems
+that are available on the system:
+.Bd -literal -offset indent
+sysctl vfs
