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 access the Expert Witness
       Compression Format (EWF).

       The options are as follows:

       -Acodepage
               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

       -bnumber_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

       -Bnumber_of_bytes
               the number of bytes to acquire

       -ccompression_values
               specify  the  compression  values  as:  level or method:level compression method options: deflate
               (default) compression level options: none (default), empty-block, fast or best

       -Ccase_number
               the case number (default is case_number)

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

       -Ddescription
               the description (default is description)

       -eexaminer_name
               the examiner name (default is examiner_name)

       -Eevidence_number
               the evidence number (default is evidence_number)

       -fformat
               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

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

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

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

       -Nnotes
               the notes (default is notes)

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

       -pprocess_buffer_size
               the process buffer size (default is the chunk size)

       -Pbytes_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)

       -Ssegment_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)

       -ttarget
               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 functions.

       -2secondary_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.

       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.
