Description:

I have two lines, lets say "-line1-" and "-line2-" and between these lines I have some lines. The amount and the content of these lines are unknown. Like this:
some lines -line1- lineA: xxx lineB: y lineC: zz -line2- more lines
So, I want to remove everything between "-line1-" and "-line2-", in this case lines A, B and C. How can I do this?

Answer: Removing everything between two lines

See perlfaq "How can I pull out lines between two patterns that are themselves on different lines?".

    [Corion]: Meh, first round of escalations for me not wanting to fix in production what a project has mismanaged. Now another project, which eats up all the resources until end of this year wants to take that task and put it on my list of things as well.
    [Corion]: So now there will be the fun of me explaining to the project that $other_project had low priority because $project has high priority. If $project picks up the task from $other_project, they also will need to reprioritize my tasks to get that done...
    [Corion]: ... of course at the cost of something else on my list of tasks for $project, as there only is a finite amount of days until $deadline.
