I think user_prady means the information needs to be printed already at the point when you see the Main Start although it occurs later in the file. So you need to either move things around in the file (the ugly multi-line regex substitution solution) or keep the stuff between Main Start and Main End in memory, and then print the number first, and then all the lines you have been keeping in memory. However, I'm afraid I don't know how to explain how to do this in more detail without repeating myself. In pseudo-code, something like
In real-world code, you have to move things around a little (figure out if you are coming out of "main start seen" as basically the first thing), but this is only pseudo-code, mind.
I'm reluctant to write code before we get confirmation that this is the actual requirement, though.
Hi
I'm not very good with the serach patterns and I'd need a sample how to find a line that has multiple patterns.
Say I want to find a line that has "abd", "123" and "QWERTY" and there can be any characters or numbers between the serach patterns, I have a file that has thousands of lines and... (10 Replies)

Acme::Brainfuck(3) User Contributed Perl Documentation Acme::Brainfuck(3)NAME
Acme::Brainfuck - Embed Brainfuck in your perl code
SYNOPSIS
#!/usr/bin/env perl
use Acme::Brainfuck;
print 'Hello world!', chr ++++++++++. ;
DESCRIPTION
Brainfuck is about the tiniest Turing-complete programming language you can get. A language is Turing-complete if it can model the opera-
tions of a Turing machine--an abstract model of a computer defined by the British mathematician Alan Turing in 1936. A Turing machine con-
sists only of an endless sequence of memory cells and a pointer to one particular memory cell. Yet it is theoretically capable of perform-
ing any computation. With this module, you can embed Brainfuck instructions delimited by whitespace into your perl code. It will be trans-
lated into Perl as parsed. Brainfuck has just just 8 instructions (well more in this implementation, see "Extensions to ANSI Brainfuck"
below.) which are as follows
Instructions
+ Increment
Increase the value of the current memory cell by one.
- Decrement
Decrease the value of the current memory cell by one.
> Forward
Move the pointer to the next memory cell.
< Back
Move the pointer to the previous memory cell.
, Input
Read a byte from Standard Input and store it in the current memory cell.
. Output
Write the value of the current memory cell to standard output.
[ Loop
If the value of the current memory cell is 0, continue to the cell after the next ']'.
] Next
Go back to the last previous '['.
Extensions to ANSI Brainfuck
This implementation has extra instructions available. In order to avoid such terrible bloat, they are only available if you use the ver-
bose pragma like so:
use Acme::Brainfuck qw/verbose/;
The extra instructions are:
~ Reset
Resets the pointer to the first memory cell and clear all memory cells.
# Peek
Prints the values of the memory pointer and the current memory cell to STDERR. See also "Debugging" below.
Debugging
By using the debug pragma like this:
use Acme::Brainfuck qw/debug/;
you can dump out the generated perl code. (Caution: it is not pretty.) The key to understanding it is that the memory pointer is repre-
sented by $p, and the memory array by @m Therefore the value of the current memory cell is $m[$p].
RETURN VALUE
Each sequence of Brainfuck instructions becomes a Perl block and returns the value of the current memory cell.
EXAMPLES

#!/usr/bin/env perl
use Acme::Brainfuck;
print "Just another ";

Countdown

use strict;
use Acme::Brainfuck qw/verbose/;
print "Countdown commencing...
";
++++++++++[>+>+<<-]
>>+++++++++++++++++++++++++++++++++++++++++++++++<<
++++++++++[>>.-<.<-]
print "We have liftoff!
";
Reverse
#!/usr/bin/env perl
use Acme::Brainfuck qw/verbose/;
while(1)
{
print "Say something to Backwards Man and then press enter: ";
+[->,----------]<
print 'Backwards Man says, "';
[+++++++++++.<]<
print "" to you too.

Math
#!/usr/bin/env perl
