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.
