I would not use LOAD DATA INFILE it is kinda of a drag compared to the much slicker mysqlimport which should be located in /usr/local/mysql/bin. Check that out you won't be dissappointed.
It's not "much slicker", it's just a command-line version of the same thing! The LOAD DATA INFILE is an SQL command; the mysqlimport is a command-line interface to that SQL command. They're used in different situations. See the docs.
