I have 14 fields are chars (like char(8), char(9)), and one field is int(4).
All char fields are mixed with upper case letters, numbers(0-9) and
sign(like $).
Because there is no low case char, I don't have to put -f option for unix sort.
Thanks.

Are all fields of binary types? If not, DISTINCT equals "sort -uf", not
"sort -u"

Hi,
I have a 76,500,000 rows table with 15 fields.
I try to sort this rows on all fields, so I am using select all fields1
group by all fields2 or distinct all fields1 with order by all fields2.
After sort, I get 62,000,000 rows.
Then I use Linux unique sort, I dump out 76,500,000 table and us
