NAME
ewfexport --- exports media data stored in EWF files
SYNOPSIS
ewfexport [-A codepage] [-b number_of_sectors] [-B number_of_bytes]
[-c compression_values] [-d digest_type] [-f format]
[-l log_filename] [-o offset] [-p process_buffer_size]
[-S segment_file_size] [-t target] [-hqsuvVwx] ewf_files
DESCRIPTION
ewfexport is a utility to export media data stored in EWF files.
ewfexport is part of the libewf package. libewf is a library to access
the Expert Witness Compression Format (EWF).
ewf_files the first or the entire set of EWF segment files
The options are as follows:
-A codepage
the codepage of header section, options: ascii (default),
windows-874, windows-932, windows-936, windows-949, windows-950,
windows-1250, windows-1251, windows-1252, windows-1253,
windows-1254, windows-1255, windows-1256, windows-1257 or
windows-1258
-b number_of_sectors
the number of sectors to read at once (per chunk), options: 16,
32, 64 (default), 128, 256, 512, 1024, 2048, 4096, 8192, 16384 or
32768
-B number_of_bytes
the number of bytes to export
-c compression_values
specify the compression values as: level or method:level
compression method options: deflate (default), bzip2 (bzip2 is
only supported by EWF2 formats) compression level options: none
(default), empty-block, fast or best
-d digest_type
calculate additional digest (hash) types besides md5, options:
sha1 (not used for raw and files formats)
-f format
the output format to write to, options: raw (default), files
(restricted to logical volume files), ewf, smart, ftk, encase1,
encase2, encase3, encase4, encase5, encase6, encase7, encase7-v2,
linen5, linen6, linen7, ewfx.
-h shows this help
-l log_filename
logs export errors and the digest (hash) to the log filename
-o offset
the offset to start the export (default is 0)
-p process_buffer_size
the process buffer size (default is the chunk size)
-s swap byte pairs of the media data (from AB to BA) (use this for
big to little endian conversion and vice versa)
-S segment_file_size
the segment file size in bytes (default is 1.4 GiB) (minimum is
1.0 MiB, maximum is 7.9 EiB for raw, encase6 and encase7 format
and 1.9 GiB for other formats) (not used for files format)
-t target
the target file to export to, use - for stdout (default is
export) stdout is only supported for the raw format
-u unattended mode (disables user interaction)
-v verbose output to stderr
-V print version
-w zero sectors on checksum error (mimic EnCase like behavior)
-x use the chunk data instead of the buffered read and write
functions.
ENVIRONMENT
None
FILES
None
EXAMPLES
ewfexport will ask the information it needs.
# ewfexport floppy.E01
ewfexport 20120805

DIAGNOSTICS
Errors, verbose and debug output are printed to stderr when verbose
output -v is enabled. Verbose and debug output are only printed when
enabled at compilation.
