This question is really about sed not python, hence it's totally off.
But since lots of unix heads are frequenting this list I thought I'd
try my luck nevertheless.
If I have a file with content
1
2
3
4
5
6
7
8
........
i.e. each line contains simply its line number, then it's quite easy
to convert it into
2
3
7
8
12
13
............
using python. The pattern is that the first line is deleted, then 2
lines are kept, 3 lines are deleted, 2 lines are kept, 3 lines are
deleted, etc, etc.
But I couldn't find a way to do this with sed and since the whole
operation is currently done with a bash script I'd hate to move to
python just to do this simple task.
What would be the sed equivalent?
Cheers,
Daniel
