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 persistant
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.
