How can I get the number of affected records, and just that, using mysql cmdline?

Question

I'm running the mysql cmdline binary to execute queries. (Specifically, I'm executing LOAD DATA LOCAL INFILE). I would like to have it print, after every statement, the number of records effected - but no other lines. I don't mind the line containing other info, e.g.

Query OK, 20 rows affected, 4 warnings

would be great. I can, in fact, get that - but only if I use the -v -v pair of switches, and then I get more info which I don't need, like an echo of the parsed command.

Can I do anything other than grep the output for the pattern of the line above?

It's maybe not the best solution, but you can try the SQL ROW_COUNT() function

E.g :

mysql ... -e "YOUR_QUERY;SELECT ROW_COUNT()" -B | tail -n 1
