.SH "DESCRIPTION"
.PP
\fByaz\-marcdump\fR
reads MARC records from one or more files\&. It parses each record and supports output in line\-format, ISO2709,
\m[blue]\fBMARCXML\fR\m[]\&\s-2\u[1]\d\s+2,
\m[blue]\fBMARC\-in\-JSON\fR\m[]\&\s-2\u[2]\d\s+2,
\m[blue]\fBMarcXchange\fR\m[]\&\s-2\u[3]\d\s+2
as well as Hex output\&.
.PP
This utility parses records ISO2709(raw MARC), line format, MARC\-in\-JSON format as well as XML if that is structured as MARCXML/MarcXchange\&.
.PP
MARC\-in\-JSON encoding/decoding is supported in YAZ 5\&.0\&.5 and later\&.

As of YAZ 2\&.1\&.18, OAI\-MARC is no longer supported\&. OAI\-MARC is deprecated\&. Use MARCXML instead\&.

.PP
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,
.PP
\fByaz\-marcdump\fR
can also be requested to perform character set conversion of each record\&.
.SH "OPTIONS"
.PP
\-i \fIformat\fR
.RS 4
Specifies input format\&. Must be one of
marcxml,
marc
(ISO2709),
marcxchange
(ISO25577),
line
(line mode MARC),
turbomarc
(Turbo MARC), or
json
(MARC\-in\-JSON)\&.
.RE
.PP
\-o \fIformat\fR
.RS 4
Specifies output format\&. Must be one of
marcxml,
marc
(ISO2709),
marcxchange
(ISO25577),
line
(line mode MARC),
turbomarc
(Turbo MARC), or
json
(MARC\-in\-JSON)\&.
.RE
.PP
\-f \fIfrom\fR
.RS 4
Specify the character set
\fIfrom\fR
of the input MARC record\&. Should be used in conjunction with option
\-t\&. Refer to the yaz\-iconv man page for supported character sets\&.
.RE
.PP
\-t \fIto\fR
.RS 4
Specify the character set
\fIof\fR
of the output\&. Should be used in conjunction with option
\-f\&. Refer to the yaz\-iconv man page for supported character sets\&.
.RE
.PP
\-l \fIleaderspec\fR
.RS 4
Specify a simple modification string for MARC leader\&. The
\fIleaderspec\fR
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=\*(Aqa\*(Aq\&.
.RE
.PP
\-s \fIprefix\fR
.RS 4
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\&.
.RE
.PP
\-C \fIchunksize\fR
.RS 4
Specifies chunk size; to be used conjunction with option
\-s\&.
.RE
.PP
\-p
.RS 4
Makes yaz\-marcdump prints record number and input file offset of each record read\&.
.RE
.PP
\-n
.RS 4
MARC output is omitted so that MARC input is only checkecd\&.
.RE
.PP
\-v
.RS 4
Writes more information about the parsing process\&. Useful if you have ill\-formatted ISO2709 records as input\&.
.RE
.PP
\-V
.RS 4
Prints YAZ version\&.
.RE
.SH "EXAMPLES"
.PP
The following command converts MARC21/USMARC in MARC\-8 encoding to MARC21/USMARC in UTF\-8 encoding\&. Leader offset 9 is set to \*(Aqa\*(Aq\&. Both input and output records are ISO2709 encoded\&.
.sp
.if n \{\
.RS 4
.\}
.nf
    yaz\-marcdump \-f MARC\-8 \-t UTF\-8 \-o marc \-l 9=97 marc21\&.raw >marc21\&.utf8\&.raw
   
.fi
.if n \{\
.RE
.\}
.PP
The same records may be converted to MARCXML instead in UTF\-8:
.sp
.if n \{\
.RS 4
.\}
.nf
    yaz\-marcdump \-f MARC\-8 \-t UTF\-8 \-o marcxml marc21\&.raw >marcxml\&.xml
   
.fi
.if n \{\
.RE
.\}
.PP
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:
.sp
.if n \{\
.RS 4
.\}
.nf
    yaz\-marcdump \-f MARC8 \-t UTF8 \-o turbomarc \-i marc marc21\&.raw >out\&.xml
