例如本機 WinXP 使用網芳或 ssh 與 vmware 上的 linux 連線

安裝步驟如下
1. [控制台]->「新增硬體]

2. 按一下 [是，我已連接這個硬體]，然後按一下 [下一步]。

3. 按一下位於清單底部的 [新增硬體裝置]，然後按一下 [下一步]。

4. 按一下 [安裝我從清單中手動選取的硬體]，再按一下 [下一步]。

5. 按一下 [網路介面卡]，再按一下 [下一步]。

6. 在 [製造商] 方塊中，按一下 [Microsoft]。

7. 在 [網路介面卡] 方塊中，按一下 [Microsoft Loopback Adapter]，然後按一下 [下一步]。

8. 按一下 [完成]。

start 123.txt   # 開啟預設文字編輯器
start http://www.google.com #開啟預設的瀏覽器
start mailto:admin@123.com //開啟預設的email軟體

若是在linux 下，使用的是gnome
gnome-open 123.txt
gnome-open http://www.google.com
gnome-open mailto:admin@123.com

example:

view plain
PERL:
  1. print <<FOO;
  2. Perl offers a convenient way of printing multiple lines of output through an interesting feature known as a "Perl here document".
  3.  
  4. A multiline Perl here document works like this:
  5. <ol>
  6.     <li>The first line of your command will include the two characters <code>&lt;&lt;</code> followed by a "special" identifier string, followed by a semi-colon. (For my example I will use the identifier string <code>FOO</code>. More on this shortly.)</li>
  7.     <li>Next, just enter all of the lines of output that you want to print.</li>
  8.     <li>When you are ready to terminate the output, put your special identifier string on a line by itself to end the output.</li>
  9. </ol>
  10. FOO

遇到反斜線需要 double。
