How to upgrade your distribution
Find out current version of Debian that you are running:

cat /etc/debian_version

Example for upgrading sarge to etch or etch 4.0r1 to 4.0r2 …etc

aptitude update

aptitude dist-upgrade

來源：Aptitude – Debian Wiki

因為用 Leopard 內建的 Python 在互動模式下中文有問題
所以來用 MacPorts 裝 Python 2.6，裝好之後出現
To fully complete your installation and make python 2.6 the default, please run

sudo port install python_select
sudo python_select python26


python_select：Switch the default python interpreter

還是自己作連結比較保險

cd /usr/bin/

sudo ln -s /opt/local/bin/python python

• 頁尾插入「第 頁，共 頁」
• Ctrl+F9，插入代碼：{page}、{numpages}
  • {page}該頁數
  • {numpages}總頁數
• Alt+F9，更新代碼
• 完成

tchinese.py

#!/bin/python
print "Python是個酷玩意"

python tchinese.py
SyntaxError: Non-ASCII character '\xe6' in file tchinese.py on line 2, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

錯誤訊息中的連結到這篇文章：PEP 0263 — Defining Python Source Code Encodings
文中提到：

To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as:

# coding=<encoding name>

or (using formats recognized by popular editors)

#!/usr/bin/python
# -*- coding: <encoding name> -*-

or

#!/usr/bin/python
# vim: set fileencoding=<encoding name> :

Example:

#!/bin/python
# -*- coding: utf-8 -*-
print "Python是個酷玩意"

Result:

Python是個酷玩意

-h　　”Human-readable” output. Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte.

PHP 檔案處理

讀檔:

1.fopen

範例:

<?php
$handle = fopen("open_file.txt", "r");
if( $handle === FALSE)
{    
    echo "Open File Fail" . "<br>";
} 
else
{    
    echo "Open File Success" . "<br>";
    while (!feof($handle))
    {
        $current_line = fgets($handle);
        echo $current_line . "<br>";
    }
}
 
?>

2.file_get_contents

範例:

<?php
 
$handle = file_get_contents('open_file.txt');
echo $handle;
 
?>

=========================================================

寫檔:

1.fwrite

<?php
$handle = fopen('open_file.txt', 'w');
fwrite($handle, "test1");
fclose($fp);
?>

ps:fwrite 是沒有加換行字元,如果要換行必須加上 \n 處理

2.file_put_contents

<?php
    $handle = 'open_file.txt';
    $current_line = "line1\n";
    file_put_contents($handle, $current_line);
?>

方便的自動安裝

perl -MCPAN -e 'install full::module::name'

但我試了幾次很容易會在 fetch ftp 來源的 source code 時卡住，要重試幾次。

手動編譯

tar xzvf example-<version>.tgz
cd example-<version>
perl Makefile.PL
make
make test
make install

搜尋WP::UserAgent模組

cpan> d /LWP::UserAgent/

重新配置cpan

cpan> o conf init
cpan> reload index

　
驗證安裝了沒

perl -e 'require LWP::UserAgent'

update: 有時候，還是需要加個 sudo 確保有權限將檔案放入系統
