Hi ,
I have a typical situation. I have 4 files and with different headers (number of headers is varible ).
I need to make such a merged file which will have headers combined from all files (comman coluns should appear once only).
For example -
File 1
H1|H2|H3|H4
11|12|13|14
21|22|23|23... (1 Reply)

Hey folks. I wrote a little awk script that summarizes /proc/net/dev info and then pipes it to the nix column command to set up column spacing appropriately.
Here's some example output:

Hi folks
I need/want to redirect output (stdout, stderr) from an exec call to separate files. One for stderr only and two(!) different (!) ones for the combined output of stderr and stdout.
After some research and testing i got this so far :

mojo::base
Mojo::Base(3pm) User Contributed Perl Documentation Mojo::Base(3pm)NAME
Mojo::Base - Minimal base class for Mojo projects
SYNOPSIS
package Cat;
use Mojo::Base -base;
has 'mouse';
has paws => 4;
has [qw(ears eyes)] => 2;
package Tiger;
use Mojo::Base 'Cat';
has stripes => 42;
package main;
use Mojo::Base -strict;
my $mew = Cat->new(mouse => 'Mickey');
say $mew->paws;
say $mew->paws(5)->ears(4)->paws;
my $rawr = Tiger->new(stripes => 23);
say $rawr->ears * $rawr->stripes;
DESCRIPTION
Mojo::Base is a simple base class for Mojo projects.
# Automatically enables "strict", "warnings" and Perl 5.10 features
use Mojo::Base -strict;
use Mojo::Base -base;
use Mojo::Base 'SomeBaseClass';
All three forms save a lot of typing.
# use Mojo::Base -strict;
use strict;
use warnings;
use feature ':5.10';
# use Mojo::Base -base;
use strict;
use warnings;
use feature ':5.10';
use Mojo::Base;
push @ISA, 'Mojo::Base';
sub has { Mojo::Base::attr(__PACKAGE__, @_) }
# use Mojo::Base 'SomeBaseClass';
use strict;
use warnings;
use feature ':5.10';
require SomeBaseClass;
push @ISA, 'SomeBaseClass';
use Mojo::Base;
sub has { Mojo::Base::attr(__PACKAGE__, @_) }
FUNCTIONS
Mojo::Base exports the following functions if imported with the "-base" flag or a base class.
"has"
has 'name';
has [qw(name1 name2 name3)];
has name => 'foo';
has name => sub {...};
has [qw(name1 name2 name3)] => 'foo';
has [qw(name1 name2 name3)] => sub {...};
Create attributes, just like the "attr" method.
METHODS
Mojo::Base implements the following methods.
"new"
my $object = BaseSubClass->new;
my $object = BaseSubClass->new(name => 'value');
my $object = BaseSubClass->new({name => 'value'});
This base class provides a basic object constructor. You can pass it either a hash or a hash reference with attribute values.
"attr"
$object->attr('name');
BaseSubClass->attr('name');
BaseSubClass->attr([qw(name1 name2 name3)]);
BaseSubClass->attr(name => 'foo');
BaseSubClass->attr(name => sub {...});
BaseSubClass->attr([qw(name1 name2 name3)] => 'foo');
BaseSubClass->attr([qw(name1 name2 name3)] => sub {...});
Create attributes. An array reference can be used to create more than one attribute. Pass an optional second argument to set a default
value, it should be a constant or a sub reference. The sub reference will be excuted at accessor read time if there's no set value.
DEBUGGING
You can set the "MOJO_BASE_DEBUG" environment variable to get some advanced diagnostics information printed to "STDERR".
MOJO_BASE_DEBUG=1
