to a specific volume or hard disk.

options
   -byte[s]   all size infos in bytes
   -tab[s]    pure values, tab separated
   -bin[ary]  calculate with binary megabytes
              of 1048576 bytes each.

aliases
   sfk diskspace  same as space
   sfk fsinfo     same as filesys
   sfk freespace  tell only free space

   sfk filesys
      tell details about the file system of the
