-Print the active vnodes.  Each group of vnodes corresponding

-.Em on fsflags

-where
-.Em fstype
-is one of
-.Em ufs , nfs , or pc ;
-.Em from

-.Em on
-is the directory
-the filesystem is mounted on; and
-.Em fsflags
-is a list
-of optional flags applied to the mount (see
-.Xr mount 8 ) .
-The second line is a header for the individual fields,
-the first part of which are fixed, and the second part are filesystem
-type specific.  The headers common to all vnodes are:
-.Bl -tag -width indent
