       filefrag - report on file fragmentation

       filefrag [ -Bbsvx ] [ files...  ]

       filefrag  reports on how badly fragmented a particular file might be.  It makes allowances
       for indirect blocks for ext2 and ext3 filesystems, but  can  be	used  on  files  for  any

       The  filefrag  program initially attempts to get the extent information using FIEMAP ioctl
       which is more efficient and faster.  If FIEMAP is not supported then  filefrag  will  fall
       back to using FIBMAP.

       -B     Force  the  use  of  the older FIBMAP ioctl instead of the FIEMAP ioctl for testing

       -b     Use 1024 byte blocksize for the output.

       -s     Sync the file before requesting the mapping.

       -v     Be verbose when checking for file fragmentation.

       -x     Display mapping of extended attributes.

       filefrag was written by Theodore Ts'o <tytso@mit.edu>.
