		      [-c compression_values] [-C case_number] [-d digest_type]
		      [-D description] [-e examiner_name] [-E evidence_number]

DESCRIPTION
     ewfacquirestream is a utility to acquire media data from stdin and store it
     in  EWF  format  (Expert  Witness Format).  ewfacquirestream acquires media
     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 ac-
     cess 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,  win-
	     dows-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 acquire

     -c compression_values
	     specify the compression values as: level or  method:level	compres-
	     sion  method  options: deflate (default) compression level options:
	     none (default), 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,  mem-
	     ory

     -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 image)

     -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  output
     -v  is  enabled.  Verbose and debug output are only printed when enabled at
     compilation.
