       rhash - calculate/check CRC32, MD5, SHA1, GOST, TTH, BTIH or other hash sums.


       rhash [ option ]... [ file ]...


       RHash  (Recursive  Hasher)  computes  and  verifies various message digests (hash sums) of
       files.  Supported message digests include CRC32, MD4, MD5,  SHA1,  SHA256,  SHA512,  SHA3,
       Tiger, DC++ TTH, BitTorrent BTIH, AICH, ED2K, GOST R 34.11-94, RIPEMD-160, HAS-160, EDON-R
       256/512, Whirlpool, Snefru-128/256.

       The program can create and verify Magnet links and eDonkey ed2k:// links, see --magnet and
       --ed2k-link options.

       A dash string parameter `-' is interpreted as stdin file.

       By  default  rhash  prints sums in SFV format with CRC32 hash sum only.  The format can be
       changed by options --bsd, --magnet, --simple, --printf, --template.  To  output  all  sums
       use the `-a' option.

       The  default  output  format  can  also  be  changed  by renaming the program or placing a
       hardlink/symlink to it with a name  containing  strings  `crc32',  `md4',  `md5',  `sha1',
       `sha256'   `sha512',   `tiger',   `tth',  `btih',  `aich',  `ed2k',  `ed2k-link',  `gost',
       `gost-cryptopro', `ripemd160', `has160', `whirlpool', `edonr256', `edonr512', `snefru128',
       `snefru256', `sfv' or `magnet'.


       The  default  mode  is  to  print hash sums for all files and directory trees specified by
       command line. The mode can be set by the following options.

       -c, --check
              Check hash files specified by command line. RHash can verify hash files in SFV  and
              BSD  formats, standard MD5 and SHA1 files, and text files containing magnet or ed2k
              links (one link per line).  Empty lines and lines starting  with  `;'  or  `#'  are
              skipped.   In  fact  RHash  can  verify most hash files generated by itself without
              formating options --printf and --template.

       -u, --update
              Update hash files specified by command line.  The program  calculates  and  appends
              hashes  to  the  updated  hash  file  in the format specified by formating options.
              Hashes are calculated for those files from the same directory  as  the  hash  file,
              which are yet not present in it.

       -k, --check-embedded
              Verify files by crc32 sum embedded in their names.

              Create a torrent file for each processed file.

       -h, --help
              Help: print help screen and exit.

              Print per-file and the total processing speed.

       -e, --embed-crc
              Rename files by inserting crc32 sum into name.

              Insert  specified  <delimiter> before a crc sum in the --embed-crc mode, default is
              white space. The <delimiter> can be a character or empty string.

              Use specified path separator to display paths.

       -q, --accept=<list>
              Set a comma‐delimited list of extensions of the files to process.

              Set a comma‐delimited list of extensions of the files to exclude from processing.

       -t, --crc-accept=<list>
              Set a comma‐delimited list of extensions of the hash files to verify.

              Descend at most <levels> (a non‐negative integer) levels of directories  below  the
              command  line  arguments.  `--maxdepth 0' means only apply the tests and actions to
              the command line arguments.

       -o, --output=<file-path>
              Set the file to output calculated hashes and verification results to.

       -l, --log=<file-path>
              Set the file to log errors and verbose information to.

              Specify which hash functions should be calculated using the OpenSSL  library.   The
              <list> is a comma delimited list of hash names, but only those supported by openssl
              are allowed, e.g. md4, md5, sha1, sha256, ripemd160.  See openssl documentation for
              the full list.

              Reverse  bytes  in  hexadecimal  output of the GOST hash sum.  The most significant
              bytes of the hash will be printed first.  Default order is  the  least  significant
              bytes first.

              Turn on torrent batch mode (implies torrent mode). Calculates batch-torrent for the
              files specified at command line and saves the torrent file to  the  file-path.  The
              option -r <directory> can be useful in this mode.

              Generate BTIH for a private BitTorrent tracker.

              Set the piece length value for torrent file.

              Add  a  tracker  announce  URL  to the created torrent file(s).  This option can be
              passed mutltiple times to add several urls.  Note that this option  doesn't  change
              the BTIH hash.

              Switch  benchmark  output  format  to be a machine‐readable tab‐delimited text with
              hash function name, speed, cpu clocks per byte.  This  option  works  only  if  the
              --benchmark option was specified.

       -- (double dash)
              Mark  the end of command line options. All parameters following the double dash are
              interpreted as files or directories. It is  typically  used  to  process  filenames
              starting  with  a dash `-'.  Alternatively you can specify './' or full path before
              such files, so they will not look like options anymore.


       --sfv  Print hash sums in the SFV (Simple File Verification) output format (default).  But
              unlike  common SFV file, not only CRC32, but any hash sums specified by options can
              be printed.

       -m, --magnet
              Print hash sums formated as magnet links.

       --bsd  Use BSD output format. Each hash sum is printed on separate line  after  hash  name
              and file's path, enclosed in parentheses.

              Use  simple  output  format.  Each  line  will  consist  of  filename and hash sums
              specified by options.

              Print hash sums in upper case.

              Print hash sums in lower case.

              Read printf‐like template from given <file>. See the --printf option.

       -p, --printf=<format>
              Format: print format string the standard output, interpreting `\' escapes  and  `%'
              directives. The escapes and directives are:

              \n     Newline.

              \r     Carriage return.

              \t     Horizontal tab.

              \\     A literal backslash (`\').

              \0     ASCII NUL.

              \NNN   The character which octal ASCII code is NNN.

              \xNN   The character which hexadecimal ASCII code is NN.

              A  `\'  character  followed  by  any  other  character  is  treated  as an ordinary
              character, so they both are printed.

              %%     A literal percent sign.

              %p     File's path.

              %f     File's name.

              %u     URL‐encoded filename.

              %s     File's size in bytes.

                     File's last modification time.

              %a or %A
                     AICH hash sum.

              %c or %C
                     CRC32 hash sum.  Use %c for lowercase and %C for uppercase characters.

              %g or %G
                     GOST R 34.11-94 hash.

              %h or %H

              %l or %L
                     EDonkey ed2k://... link.

              %m or %M
                     MD5 hash.

              %r or %R
                     RIPEMD-160 hash.

              %t or %T
                     TTH sum.

              %w or %W
                     Whirlpool hash.

              %{md4}, %{sha-224}, %{sha-256}, %{sha-384}, %{sha-512},  %{sha3-224},  %{sha3-256},

                     Print specified hash sum. Actually the %{<hash sum>} directive can print any
                     supported hash sum. If a hash sum name starts with a capital letter then the
                     hash is printed in uppercase, e.g. %{TTH}, %{Sha-512}.

              %x<hash>, %b<hash>, %B<hash>, %@<hash>
                     Use one of these prefixes to output  a  hash  sum  in  hexadecimal,  base32,
                     base64 or raw (binary) format respectively, e.g. %b{md4}, %BH or %xT.


       RHash looks for a config file at $HOME/.rhashrc and /etc/rhashrc.

       The config file consists of lines formated as
              variable = value

       where  the  variable  can  be  a  name  of  any  command line option, like magnet, printf,
       percents, etc.  A boolean variable can be set to true by a value `on',  `yes'  or  `true',
       any other value sets the variable to false.

       Empty lines and lines starting with `#' or `;' are ignored.

       Example config file:
       # This is a comment line
       percents = on
       crc-accept = .sfv,.md5,.sha1,.sha256,.sha512,.tth,.magnet
