Question: How do you find a paragraph break in perl?
Synopsis: In a string I need to find the paragraph breaks and replace
it with a ^P. Here is my code.

$my text = 'This is the FIRST paragraph.
This is the SECOND paragraph.';
print

My desired output is: This is the FIRST paragraph^PThis is the SECOND paragraph

Does perl allow you to conditionally include a module?
For example:

my $DEBUG = 0;
if (DEBUG) {

Can you use some sort of 'tail' command to get the last lines?

To get the value of the key called Beans you use $vegetable_costs{Beans} .

I have a 2 gig log file and I need to read only the last 10 lines.
I was also thinking something like:
1. Read in File
2. Get number of lines
3. Print last ten lines
or something like that.
