       available for  file  systems  by	 examining  the	 counts	 kept  in  the
       superblock  or  superblocks.  If a special or a directory is not speci‐
       fied, the free space on all mounted file systems is displayed.  If  the
       arguments to are path names, reports on the file systems containing the
       named files.  If the argument to is a special of an unmounted file sys‐
       tem, the free space in the unmounted file system is displayed.
