DESCRIPTION
     ewfacquirestream is a utility to acquire media data from stdin and	store
     it	in EWF format (Expert Witness Format).	ewfacquirestream acquires me-
     dia data in a format equivalent to	EnCase and FTK imager, including meta
     data. Under Linux,	FreeBSD, NetBSD, OpenBSD, MacOS-X/Darwin

     ewfacquirestream is part of the libewf package.  libewf is	a library to
     access the	Expert Witness Compression Format (EWF).

     The options are as	follows:

     -A	codepage
	     the codepage of header section, options: ascii (default), win-
	     dows-874, windows-932, windows-936, windows-949, windows-950,
	     windows-1250, windows-1251, windows-1252, windows-1253, win-
	     dows-1254,	windows-1255, windows-1256, windows-1257 or win-
	     dows-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 acquire

     -c	compression_values
	     specify the compression values as:	level or method:level compres-
	     sion method options: deflate (default), bzip2 (bzip2 is only sup-
	     ported by EWF2 formats) compression level options:	none (de-
	     fault), empty-block, fast or best

     -C	case_number
	     the case number (default is case_number)

     -d	digest_type
	     calculate additional digest (hash)	types besides md5, options:
	     sha1, sha256

     -D	description
	     the description (default is description)

     -e	examiner_name
	     the examiner name (default	is examiner_name)

     -E	evidence_number
	     the evidence number (default is evidence_number)

     -f	format
	     the EWF file format to write to, options: ftk, encase2, encase3,
	     encase4, encase5, encase6 (default), encase7, linen5, linen6,
	     linen7, ewfx.  libewf does	not support streamed writes for	other
	     EWF formats.

     -h	     shows this	help

     -l	log_filename
	     logs acquiry errors and the digest	(hash) to the log filename

     -m	media_type
	     the media type, options: fixed (default), removable, optical,
	     memory

     -M	media_flags
	     the media flags, options: logical,	physical (default)

     -N	notes
	     the notes (default	is notes)

     -o	offset
	     the offset	to start to acquire (default is	0)

     -p	process_buffer_size
	     the process buffer	size (default is the chunk size)

     -P	bytes_per_sector
	     the number	of bytes per sector (default is	512)

     -q	     quiet shows minimal status	information

     -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 encase6 and encase7 format	and
	     1.9 GiB for other formats)

     -t	target
	     the target	file (without extension) to write to (default is im-
	     age)

     -v	     verbose output to stderr

     -V	     print version

     -x	     use the chunk data	instead	of the buffered	read and write func-
	     tions.

     -2	secondary_target
	     the secondary target file (without	extension) to write to

     ewfacquirestream will read	from stding until it encounters	a read error.
     On	read error it will stop	no error information is	stored in the EWF
     file(s).

     Empty block compression detects blocks of sectors with entirely the same
     byte data and compresses them using the default compression level.

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