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,
   MarcXchange as well as Hex output.

   This utility parses records ISO2709(raw MARC) as well as XML if that is
   structured as MARCXML/MarcXchange.

       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), or turbomarc (Turbo
       MARC).

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

   -f from
       Specify the character set from 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 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 record 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 prints record number and input file offset of
       each record read.

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

   -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
