read the file line by line.  if it doesn't contain your string, write
it to a new file.  for each line, use string functions to find the
string you want to remove.  One way is to split on ',' or use
csvreader to get a list of words between comma.  Print the one you
like and join the values on each side of the text you are looking for.
Write that to a file

Lather, rinse and repeat
