Both load data infile and mysqlimport both support the ignore option.
If you are loading a file into a table with a unique index and
duplicate rows in the file any duplicates will be silently ignored.

thanks for the reply! I am not too concerned about cutting out the columns
as I may need to other information for later.
I was just wondering does it make a difference if both of the columns that
I am interested have entries that are NOT unique?
Also, at what point does one need a parser or use
awk is probably the best tool I can think of for cutting columns out
of a text file. Something like
awk -F \\t '{ print $2 "," $3 }' my_file
could be used to pick the second and third column out of a file prior
to importing it.
