scalpel - Recover files using a header/footer database
scalpel [-b] [-c <file>] [-d] [-h] [-i <file>] [-m <blocksize>] [-n]
[-o <dir>] [-O] [-p] [-r] [-s <num>] [-t] [-u] [-V] [-v] [FILES]...
Recover files from a disk image or raw block device based on headers
and footers specified by the user.
-b Carve files even if defined footers aren't discovered within
maximum carve size for file type [foremost 0.69 compat mode]
Chooses which configuration file to use. If this option is
omitted, then "scalpel.conf" in the current directory is used.
The format for the configuration file is described in the
default configuration file "scalpel.conf". See the
CONFIGURATION FILE section below for more information.
-d Generate header/footer database; will bypass certain
optimizations and discover all footers, so performance suffers.
Doesn't affect the set of files carved. **EXPERIMENTAL**
-m Generate/update carve coverage blockmap file. The first 32bit
unsigned int in the file identifies the block size. Thereafter
each 32bit unsigned int entry in the blockmap file corresponds
to one block in the image file. Each entry counts how many
carved files contain this block. Requires more memory and disk.
-h Show a help screen and exit.
file is used as a list of input files to examine. Each line in
the specified file should contain a single filename.
Recovered files are written to the directory directory.
Scalpel requires that this directory be either empty or not
exist. The directory will be created if necessary.
-O Don't organize carved files by type. Default is to organize
carved files into subdirectories to make previewing of large
numbers of carved files easier.
-p Perform image file preview; audit log indicates which files
would have been carved, but no files are actually carved.
Carve only when header is cluster-aligned.
-r Find only first of overlapping headers/footers [foremost 0.69
Skips number bytes in each input file before beginning the
search for file headers and footers.
-t Set directory for coverage blockmap. **EXPERIMENTAL**
-u Use carve coverage blockmap when carving. Carve only sections
of the image whose entries in the blockmap are 0. These areas
are treated as contiguous regions. **EXPERIMENTAL**
-V Show copyright information and exit.
-v Enables verbose mode. This causes copious amounts of debugging
information to be output.
The configuration file is used to control the types of files Scalpel
will attempt to carve. A sample configuration file, "scalpel.conf", is
included with this distribution. For each file type, the configuration
file describes the file's extension, whether the header and footer are
case sensitive, the maximum file size, and the header and footer for
the file. The footer field is optional, but the header, size, case
sensitivity, and extension fields are required.
Important note: The default configuration file has all supported file
patterns commented out--you must edit this before before running
Any line in the configuration file that begins with a pound sign is
considered a comment and ignored.
Headers and footers are decoded before use. To specify a value in
hexadecimal use \x[0-f][0-f], and for octal use \[1-9][1-9][1-9].
Spaces can be represented by \s. Example: "\x4F\123\I\sCCI" decodes to
To match any single character (aka a wildcard) use a '?'. If you need
to search for the '?' character, you will need to change the 'wildcard'
line *and* every occurrence of the old wildcard character in the
configuration file, including those appearing in hex and octal values.
'?' is equal to \x3f and \063.

BUGS AND LIMITATIONS
It is currently not possible to carve physical block devices directly
using the Windows version of Scalpel. This is a limitation that will
be removed in a future release of Scalpel.
