If you wanted to do it a a shell script, you could iterate through the files and run sed on them
It would look
something like this
Code:
for each filename in /myDirectory do
sed -n -e '/<br \/>/d' filename
end for
But, as a warning. I have not tested this code, this is simply an approach that you can start from. Try googling 'loop through files with bash' and 'sed guides'. I strongly advise that you start working this stuff out for yourself. I don't think the kind of spoon feeding you're getting here is in your best interests.
