620 --output -o Cleaned MARCXML output filename
621 --exception -x Exception (dumped records) MARCXML filename
623 --prefix=<PREFIX>> -p Shared prefix for output/exception files. Will produce
624 PREFIX.clean.marc.xml and PREFIX.exception.marc.xml
626 --renumber-from -rf Begin renumbering id sequence with this number
627 --renumber-tag -rt Tag to use in renumbering (default: 903)
628 --renumber-subfield -rs Subfield code to use in renumbering (default: a)
629 --original-tag -ot Original id tag; will be kept in output even if
630 it appears in the trash file
631 --original-subfield -os Original id subfield code. If this is specified
632 and renumbering is in effect, an old-to-new mapping
633 file (old2new.map) will be generated.
635 --autoscrub -a Automatically remove non-numeric tags in data
636 --nocollapse -n Don't compress records to one line on output
637 --no-strip9 Don't autoremove 901/903 tags in data
638 --trashfile -t File containing trash tag data (see --trashhelp)
641 --script Store human-initiated ops in scriptfile (.mcscript)
