NAME

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

SYNOPSIS

       scrub [options] paths...

DESCRIPTION

       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.

OPTIONS

       --blocksize size
              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.
