It now responds to: -n : the number of records to import. -commit : the number of records to wait before performing a 'commit' operation ALSO: IMPORTANT: I took out the char_encoding as this should be handled by MARC::File::XML now, unless I'm mistaken.

parameters :
|
|
\th : this version/help screen
|
|
\tfile /path/to/file/to/dump : the file to dump
|
|
\tv : verbose mode. 1 means "some infos", 2 means "MARC dumping"
|
|
\tn : the number of records to import. If missing, all the file is imported
|
|
\tcommit : the number of records to wait before performing a 'commit' operation
|
|
\tt : test mode : parses the file, saying what he would do, but doing nothing.
|
|
\tc : the char encoding. At the moment, only MARC21 and UNIMARC supported. MARC21 by default.
|
|
\td : delete EVERYTHING related to biblio in koha-DB before import :tables :
|
|
\t\tbiblio, \t\tbiblioitems, \t\tsubjects,\titems
|
|
\t\tadditionalauthors, \tbibliosubtitles, \tmarc_biblio,
|
|
\t\tmarc_subfield_table, \tmarc_word, \t\tmarc_blob_subfield
|
|
IMPORTANT : don't use this script before you've entered and checked your MARC parameters tables twice (or more!).
|
|
Otherwise, the import won't work correctly and you will get invalid data.
