YAZ-MARCDUMP(1)                    Commands                    YAZ-MARCDUMP(1)



NAME
       yaz-marcdump - MARC record dump utility

SYNOPSIS
       yaz-marcdump [-i format] [-o format] [-f from] [-t to] [-l spec]
                    [-c cfile] [-s prefix] [-C size] [-n] [-p] [-v] [-V]
                    [file...]

DESCRIPTION
       yaz-marcdump reads MARC records from one or more files. It parses each
       record and supports output in line-format, ISO2709, MARCXML[1],
       MARC-in-JSON[2], MarcXchange[3] as well as Hex output.

       This utility parses records ISO2709(raw MARC), line format,
       MARC-in-JSON format as well as XML if that is structured as
       MARCXML/MarcXchange.

       MARC-in-JSON encoding/decoding is supported in YAZ 5.0.5 and later.

           Note
           As of YAZ 2.1.18, OAI-MARC is no longer supported. OAI-MARC is
           deprecated. Use MARCXML instead.

       By default, each record is written to standard output in a line format
       with newline for each field, $x for each subfield x. The output format
       may be changed with option -o,

       yaz-marcdump can also be requested to perform character set conversion
       of each record.

OPTIONS
       -i format
           Specifies input format. Must be one of marcxml, marc (ISO2709),
           marcxchange (ISO25577), line (line mode MARC), turbomarc (Turbo
           MARC), or json (MARC-in-JSON).

       -o format
           Specifies output format. Must be one of marcxml, marc (ISO2709),
           marcxchange (ISO25577), line (line mode MARC), turbomarc (Turbo
           MARC), or json (MARC-in-JSON).

       -f from
           Specify the character set of the input MARC record. Should be used
           in conjunction with option -t. Refer to the yaz-iconv man page for
           supported character sets.

       -t to
           Specify the character set of the output. Should be used in
           conjunction with option -f. Refer to the yaz-iconv man page for
           supported character sets.

       -l leaderspec
           Specify a simple modification string for MARC leader. The
           leaderspec is a list of pos=value pairs, where pos is an integer
           offset (0 - 23) for leader. Value is either a quoted string or an
           integer (character value in decimal). Pairs are comma separated.
           For example, to set leader at offset 9 to a, use 9='a'.

       -s prefix
           Writes a chunk of records to a separate file with prefix given,
           i.e. splits a record batch into files with only at most "chunk"
           ISO2709 records per file. By default chunk is 1 (one record per
           file). See option -C.

       -C chunksize
           Specifies chunk size; to be used conjunction with option -s.

       -p
           Makes yaz-marcdump print record number and input file offset of
           each record read.

       -n
           MARC output is omitted so that MARC input is only checked.

       -v
           Writes more information about the parsing process. Useful if you
           have ill-formatted ISO2709 records as input.

       -V
           Prints YAZ version.

EXAMPLES
       The following command converts MARC21/USMARC in MARC-8 encoding to
       MARC21/USMARC in UTF-8 encoding. Leader offset 9 is set to 'a'. Both
       input and output records are ISO2709 encoded.

               yaz-marcdump -f MARC-8 -t UTF-8 -o marc -l 9=97 marc21.raw >marc21.utf8.raw


       The same records may be converted to MARCXML instead in UTF-8:

               yaz-marcdump -f MARC-8 -t UTF-8 -o marcxml marc21.raw >marcxml.xml


       Turbo MARC is a compact XML notation with same semantics as MARCXML,
       but which allows for faster processing via XSLT. In order to generate
       Turbo MARC records encoded in UTF-8 from MARC21 (ISO), one could use:

               yaz-marcdump -f MARC8 -t UTF8 -o turbomarc -i marc marc21.raw >out.xml
