#!/bin/bash

#default iocharset(nls)，设定默认编码为 utf8
charset=utf8
echo "The default charset(nls) is $charset"
if [ $1 ]; then
    #如果参数1不为空，则认为是手工指定了新的编码，将新的编码存储…
    charset=$1
    echo "charset is set to $charset"
fi

#begin mount with $charset...　挂载…
mount /dev/hda1 /mnt/c -r -o nls=$charset
mount /dev/hda5 /mnt/d -r -o nls=$charset

小结： 此次编写 sh 脚本学习了：

• 如何对变量赋值。在例子中：charset=utf8
• 如何用 if 语句
• 如何获得参数。在例子中：charset=$1
• 如何判断字符串不为空。在例子中：[ $1 ]
