sort -f -u -t , –key=2,51 cumindex.tab.txt > cumindex_unique.tab.txt

Export the table, sort removing duplicate keys, import.

But I'm having trouble adapting your Technique 1 for a particular purpose. I would like to eliminate duplicates only if they have a certain value for a given column (in this case "lang='0'"). (I plan then to do a second pass to get rid of the rest by MIN id.) Seems to be a case for a WHERE clause but I just can't figure out how to construct the query. Ideas appreciated! Really helpful stuff, thanks!
