       This  command is used to securely erase files.  This is accomplished by filling the file with random data
       in pre-sized chunks.  Multiple passes of random data may also be used.  The pre-sized chunks are used  to
       remove information about exact original file size.  Other options include random renaming of the original
       file  before deletion and the use of truncation to break down meta-data on what blocks in the file system
       were originally associated with a securely deleted file.  This is specifically intended to make it harder
       to perform forensic analysis on securely erased files.

       scrub-files - securely erase files by filling with random data first.

--blocksizesize
              Set the default block size (in 1 k increments) for scrub-files to use when  writing  random  data.
              This  effects both the final file length, which will be aligned to the specified size, and the way
              the truncate option decomposes files.  The default is 1k.

       --follow
              Dereference and follow symlinks, erasing the target file.

       --passes=count
              The number of passes used when writing random data.  The default is 1 pass.

       --recursive
              If argument is a directory, recursively scan directory and any subdirectory contents as arguments.

       --rename
              Rename the file randomly before deletion to clear persistent inode data.

       --truncate
              Decompose the file through truncation to break down file system page maps.

       --verbose
              Display each file being processed to the console.

       --help Outputs help screen for the user.
