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.

  • Not perl, right now i am just testing testing the expression on the site. the only difference here is the is "?" Quantifier. i think that should the trick. running are test now. thank you for the quick response. – user68650 Apr 10 '16 at 19:28
