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. +.El +.Sh ENVIRONMENTAL VARIABLES +.Bl -tag -width BLOCKSIZE +.It Ev BLOCKSIZE +If the environmental variable +.Ev BLOCKSIZE +is set, the block counts will be displayed in units of that size block. +.El +.Sh BUGS +The +.Fl n +and +.Fl t +flags are ignored if a file or filesystem is specified. +.Sh SEE ALSO +.Xr quota 1 , +.Xr statfs 2 , +.Xr fstatfs 2 , +.Xr getfsstat 2 , +.Xr getmntinfo 3 , +.Xr fstab 5 , +.Xr mount 8 , +.Xr quot 8 +.Sh HISTORY +A +.Nm df +command appeared in +.At v6 . |
