Answer 1

Using the perl regexp engine (you did not specify what you are using), this can be achieved with:

perl -pe 's/^(.*?)( \(|-tt).*/\1/' < indata.txt

The trick is to make the first .* match non-greedy with .*?, or it will consume the year part for any line that has both a year and the -tt id.
