removing lines between two patterns (not inclusive) with sed

Question

Ok

I know that this is trivial question but: How can i remove lines from files that are between two known patterns/words:

pattern1
garba

Answer 1

This is easily done with awk:

BEGIN { doPrint = 1; }
/pattern1/ { doPrint = 0; print $0; }
/pattern2/ { doPrint = 1; }
{ if (doPrint) print $0; }

I've found the sed info is fairly easy reading, with many examples. Same thing for awk.
