184280	2016-07-07	cif/9/ Marking 756 entries in range 9* as duplicates of other entries in the COD. All entries, containing '_cod_database_code' in their titles, were copied to a separate MySQL table 'duplicates' for comparison of the rest of their titles against the "original" entries. Formulae, both given by authors and calculated, were not compared, since duplicate entries in range 9* do not contain Z values. Command to compare and mark the duplicates: mysql -u root duplicates9 -p -e 'select A.file, B.file from data as A join duplicates as B on A.file = B.duplicateof and replace(replace(replace(A.title, "~", ""), " ", ""), "$-", "") = replace(B.title, " ", "") where A.duplicateof is null' -N \ \| while read -a LINE; \ do \ cat $(cod-locate ${LINE[1]}) <(echo _cod_duplicate_entry ${LINE[0]}) \ \| cif_filter -h $(cod-locate ${LINE[1]}) \ \| sponge $(cod-locate ${LINE[1]}); \ done	9015156.cif
