filter parts of a big file using awk or sed script
I need an assistance in file generation using awk, sed or anything...
I have a big file that i need to filter desired parts only. The objective is to select (and print) the report # having the string "apple" on 2 consecutive lines in every report. Please note that the "apple" line has a HEX characters corresponding to it, that makes it really hard for me to filter this one out.
For simplicity, I used this sample file below. I appreciate all the help,as always....
thanks,
apalex
INPUT FILE:
-----------
REPORT #001
apple h'1
apple h'1
banana h'2
orange h'3
kiwi h'4

REPORT #002
apple h'1
banana h'2
orange h'3
kiwi h'4

apple h'1
apple h'1
banana h'2
orange h'3

REPORT #005
apple h'1
banana h'2
orange h'3
kiwi h'4

OUTPUT FILE (two "apple" in a report)
------------
REPORT OUTPUT #001
apple h'1
apple h'1
banana h'2
orange h'3
kiwi h'4

yaml::node
YAML::Node(3) User Contributed Perl Documentation YAML::Node(3)
NAME
YAML::Node - A generic data node that encapsulates YAML information
SYNOPSIS
use YAML;
use YAML::Node;
my $ynode = YAML::Node->new({}, 'ingerson.com/fruit');
%$ynode = qw(orange orange apple red grape green);
print Dump $ynode;
yields:
--- !ingerson.com/fruit
orange: orange
apple: red
grape: green
DESCRIPTION
A generic node in YAML is similar to a plain hash, array, or scalar node in Perl except that it must also keep track of its type. The type
is a URI called the YAML type tag.
YAML::Node is a class for generating and manipulating these containers. A YAML node (or ynode) is a tied hash, array or scalar. In most
ways it behaves just like the plain thing. But you can assign and retrieve and YAML type tag URI to it. For the hash flavor, you can also
assign the order that the keys will be retrieved in. By default a ynode will offer its keys in the same order that they were assigned.
YAML::Node has a class method call new() that will return a ynode. You pass it a regular node and an optional type tag. After that you can
use it like a normal Perl node, but when you YAML::Dump it, the magical properties will be honored.
This is how you can control the sort order of hash keys during a YAML serialization. By default, YAML sorts keys alphabetically. But notice
in the above example that the keys were Dumped in the same order they were assigned.
YAML::Node exports a function called ynode(). This function returns the tied object so that you can call special methods on it like
->keys().
keys() works like this:
use YAML;
use YAML::Node;
%$node = qw(orange orange apple red grape green);
$ynode = YAML::Node->new($node);
ynode($ynode)->keys(['grape', 'apple']);
print Dump $ynode;
produces:
---
grape: green
apple: red
It tells the ynode which keys and what order to use.
ynodes will play a very important role in how programs use YAML. They are the foundation of how a Perl class can marshall the Loading and
Dumping of its objects.
The upcoming versions of YAML.pm will have much more information on this.
