Need to find only unique values for a given tag across the files:
For eg:
Test1:
<Tag1>aaa</Tag1>
<Tag2>bbb</Tag2>
<Tag3>ccc</Tag3>
Test2:
<Tag1>aaa</Tag1>
<Tag2>ddd</Tag2>
<Tag3>eee</Tag3>
Test3:
<Tag1>aaa</Tag1>
<Tag2>ddd</Tag2>
<Tag3>eee</Tag3>
Test4: (8 Replies)
Hi all,

Hi everyone,
I'm just wondering how could I using awk language merge two files by comparison of one their row.
I mean, I have one file like this:
file#1:
21/07/2009 11:45:00 100.0000000 27.2727280
21/07/2009 11:50:00 75.9856644 25.2492676

Hi, this is about sorting a very large file (like 10 gb) to keep lines with unique entries across SOME of the columns.
The line originally looked like this:
sort -u -k2,2 -k3,3n -k4,4n -k5,5n -k6,6n file_unsorted > file_sorted
please note the -u flag.
The problem is that this single... (4 Replies)
Hi. I am not sure the title gives an optimal description of what I want to do.
I have several text files that contain data in many columns. All the files are organized the same way, but the data in the columns might differ. I want to count the number of times data occur in specific columns,... (0 Replies)
Good morning all,
I have a problem that is one step beyond a standard awk compare.
I would like to compare three files which have several thousand records against a fourth file. All of them have a value in each row that is identical, and one value in each of those rows which may be duplicated... (1 Reply)

Padre::Document::Perl::Beginner(3pm) User Contributed Perl Documentation Padre::Document::Perl::Beginner(3pm)NAME
Padre::Document::Perl::Beginner - naive implementation of some beginner specific error checking
SYNOPSIS
use Padre::Document::Perl::Beginner;
my $beginner = Padre::Document::Perl::Beginner->new;
if (not $beginner->check($data)) {
warn $beginner->error;
}
DESCRIPTION
This is a naive implementation. It needs to be replaced by one using PPI.
In Perl 5 there are lots of pitfalls the unaware, especially the beginner can easily fall in. While some might expect the Perl compiler
itself would catch those it does not (yet ?) do it. So we took the initiative and added a beginners mode to Padre in which these extra
issues are checked. Some are real problems that would trigger an error anyway we just make them a special case with a more specific error
message. (e.g. "use warning;" without the trailing s) Others are valid code that can be useful in the hands of a master but that are
poisonous when written by mistake by someone who does not understand them. (e.g. "if ($x = /value/) { }" ).
This module provides a method called "check" that can check a Perl script (provided as parameter as a single string) and recognize
problematic code.
Examples
See <http://padre.perlide.org/ticket/52> and <http://www.perlmonks.org/?node_id=728569>
Cases
o
split /,/, @data;
Here @data is in scalar context returning the number of elements. Spotted in this form:
split /,/, @ARGV;
o
use warning;
s is missing at the end.
o
map { $_; } (@items),$extra_item;
is the same as
map { $_; } (@items,$extra_item);
but you usually want
(map { $_; } (@items)),$extra_item;
which means: map all @items and them add $extra_item without mapping it.
o Warn about Perl-standard package names being reused
package DB;
o
$x = chomp $y;
print chomp $y;
o
map { s/foo/bar/; } (@items);
This returns an array containing true or false values (s/// - return value).
Use
map { s/foo/bar/; $_; } (@items);
to actually change the array via s///.
o
<@X>
o
if ($x = /bla/) {
}
o Pipe | in open() not at the end or the beginning.
o
open($ph, "| something |");
o Regular expression starting with a quantifier such as
/+.../
o
} else if {
o
} elseif {
o
close;
HOW TO ADD ANOTHER ONE
Please feel free to add as many checks as you like. This is done in three steps:
Add the test
Add one (or more) tests for this case to t/75-perl-beginner.t
The test should be successful when your supplied sample fails the check and returns the correct error message. As texts of error messages
may change, try to match a good part which allows identification of the message but don't match the very exact text.
Tests could use either one-liners written as strings within the test file or external support files. There are samples for both ways in the
test script.
Add the check
Add the check to the check-sub of this file (Document/Perl/Beginner.pm). There are plenty samples here. Remember to add a sample (and maybe
short description) what would fail the test.
Run the test script to match your test case(s) to the new check.
Add the configuration option
Go to Config.pm, look for the beginner error checks configuration and add a new setting for your new check there. It defaults to 1 (run the
check), but a user could turn it off by setting this to 0 within the Padre configuration file.
