Rename files with the command interpreter sh

2008-05-26T09:28:00.000-07:00

sh is the standard command interpreter for the system.

ifi - input + filter + interpreter

Step 1:

$ ls Run*
Run this to install syntax and clip files for jEdit.ahk
Run this to install syntax and clip files for PSPad.ahk
Run this to install syntax and clip library files for TextPad.ahk
Run this to install syntax and cliptext files for EditPlus.ahk
Run this to install syntax file for MED.ahk
Run this to install syntax file for Notepad++.ahk
Run this to install syntax highlighting for ConTEXT.ahk
Run this to install syntax highlighting for UltraEdit.ahk

Step 2:

$ ls Run*| sed -r 's/.* (.*.ahk)/& => \1/'
Run this to install syntax and clip files for jEdit.ahk => jEdit.ahk
Run this to install syntax and clip files for PSPad.ahk => PSPad.ahk
Run this to install syntax and clip library files for TextPad.ahk => TextPad.ahk
Run this to install syntax and cliptext files for EditPlus.ahk => EditPlus.ahk
Run this to install syntax file for MED.ahk => MED.ahk
Run this to install syntax file for Notepad++.ahk => Notepad++.ahk
Run this to install syntax highlighting for ConTEXT.ahk => ConTEXT.ahk
Run this to install syntax highlighting for UltraEdit.ahk => UltraEdit.ahk

Step 3:

$ ls Run*| sed -r 's/.* (.*.ahk)/mv & \1/'
mv Run this to install syntax and clip files for jEdit.ahk jEdit.ahk
mv Run this to install syntax and clip files for PSPad.ahk PSPad.ahk
mv Run this to install syntax and clip library files for TextPad.ahk TextPad.ahk
mv Run this to install syntax and cliptext files for EditPlus.ahk EditPlus.ahk
mv Run this to install syntax file for MED.ahk MED.ahk
mv Run this to install syntax file for Notepad++.ahk Notepad++.ahk
mv Run this to install syntax highlighting for ConTEXT.ahk ConTEXT.ahk
mv Run this to install syntax highlighting for UltraEdit.ahk UltraEdit.ahk

Step 4:

$ ls Run*| sed -r 's/.* (.*.ahk)/mv "&" \1/'
mv "Run this to install syntax and clip files for jEdit.ahk" jEdit.ahk
mv "Run this to install syntax and clip files for PSPad.ahk" PSPad.ahk
mv "Run this to install syntax and clip library files for TextPad.ahk" TextPad.ahk
mv "Run this to install syntax and cliptext files for EditPlus.ahk" EditPlus.ahk
mv "Run this to install syntax file for MED.ahk" MED.ahk
mv "Run this to install syntax file for Notepad++.ahk" Notepad++.ahk
mv "Run this to install syntax highlighting for ConTEXT.ahk" ConTEXT.ahk
mv "Run this to install syntax highlighting for UltraEdit.ahk" UltraEdit.ahk

Step 5:

$ ls Run*| sed -r 's/.* (.*.ahk)/mv "&" \1/'| sh

Other example: .texi -> .CCCAA

$ ls *.texi| sed 's/.*/ mv & `basename & .texi`.CCCAA/'|sh

Passando variáveis para o sed.

2008-05-26T07:18:00.000-07:00

Para usar variáveis no sed nao use ' aspas simples, apenas " aspas dupals
veja os exeplos:

exemplo 01:

$ var=value
$ echo TEXT| sed "s/T/$var/"
valueEXT

exemplo 02:

$ var=T
$ echo TEXT| sed "s/$var/V/g"
VEXV

The Human Element

2008-03-14T05:24:00.001-07:00

For each of us,
there is a moment of discovery.
We turn a page,
we raise a hand.
And just then, in the flash of a synapse,
we learn that life is elemental.
And this knowledge changes everything.
We look around and see the grandness of the scheme.
Sodium bonding with chlorine,
carbon bonding with oxygen,
hydrogen bonding with oxygen.
We see all things connected.
We see life unfold.
And in the dazzling brilliance of this knowledge,
we may overlook the element not listed on the chart.
Its importance so obvious,
its presence is simply understood.
The missing element
is the human element.
And when we add it to the equation,
the chemistry changes.
Every reaction is different.
Potassium looks to bond with potential.
Metals behave with hardened resolve.
And hydrogen and oxygen form desire.
The human element
is the element of change.
It gives us our footing to stand fearlessly
and face the future.
It is a way of seeing
that gives us a way of touching.
Issues,
ambitions,
lives.
The human element.
Nothing is more fundamental.
Nothing more elemental.

Louis Vuitton first TV ad [where will life take you?]

2008-03-14T05:22:00.000-07:00

What is a journey?
A journey is not a trip.
It's not a vacation.
It's a process. A discovery.
It's a process of self-discovery.
A journey brings us face to face with ourselves.
A journey shows us not only the world,
but how we fit in it.
Does the person create the journey
or does the journey create the person?
The journey is life itself.
Where will life take you?

Chevron "Untapped Energy"

2008-03-14T04:59:00.000-07:00

And outside the debate rages
Oil,
energy,
the environment

It is the story of our time
and it is definitive
and it's all encompassing
and it leaves no one untouched.

Because make no mistake.
This isn't just about oil companies.

This is about you and me
and the undeniable truth that at this moment there are 6.5 billion
people on this planet.

And by year's end there will be another 73 million
and every one of us will need energy to live.

Where will it come from?

This is our challenge each day.
Because for today and tomorrow
and the foreseeable future,
our lives demand oil.
But what's also true is that we can provide it more intelligently,
more efficiently,
more respectfully.

That we'll never stop looking for alternatives.
That an oil company can practice and espouse conservation.
Yes we are an oil company,
but right now we're also providing natural gas,
solar,
hydrogen,
geothermal...
Because we live on this planet too.

This is who we are.

In 180 countries.
Not corporate titans,
but men and women of vision.
58,000 citizens of the world.
Liberals and conservatives,
engineers and scientists,
pipeline welders and geologists,
husbands and wives,
part-time poets and coaches.
People who daily try to find newer ways,
cleaner ways,
to power the world.
Humans have always reached for what seemed impossible.
Because it is then that we find a way.

Tell us it can't be done
and watch as we tap the greatest source of energy in the world.

Ourselves.

This is the power of human energy.

Funções Recursivas no vim

2008-02-12T08:15:00.000-08:00

Programas Recursivos

Recursao ocorre frequentemente em computação e em matemática, tanto na forma de definições recursivas como na de algorítmos. O princípio de inducao dos numeros naturais é baseado no fato de que qualquer natural ou é 0 (zero) ou é o sucessor de um natural.

por exemplo:

definir uma funcao F sobre os naturais por recursão: dando o seu valor no
ponto 0 e descrevendo como se obtem F(n+1) a partir de F(n). Um exemplo
típico é o do fatorial, que pode ser definido da seguinte forma:

Operação FATORIAL(N:inteiro) -->inteiro
início
  se N = 0
      então devolva 1
  senão devolva FATORIAL( N - 1 ) * N
  fim_se
fim

Em Vim-Script teriamos:

$ cat  > fatorial.vim
function Fatorial(N)
    if a:N==0
        return 1
    endif
    return Fatorial( a:N - 1 ) * a:N
endfunction
^D
$ vi -c 'so fatorial.vim| echo Fatorial(6)'
:720
