请教一个入门问题

cashlu

脚本是这样的，询问名字，如果名字是Cash，则在屏幕输出“Welcome Sir!”，如果名字是非“Cash”，则输出"lease get out!"
以下是我写的脚本，但是问题在于，不论我输入什么名字，他都会输出“Welcome Sir!”



#!/bin/sh

echo What is your name?
read $name
if [ $name="Cash" ]; then
    echo "Welcome Sir!"
else
    echo "Lease Get Out!"
fi
exit 0

#!/bin/sh

echo What is your name?
read name
if [ $name = "Cash" ]; then
echo "Welcome Sir!"
else
echo "Lease Get Out!"
fi

谢谢啊！

顺便再请教一下，为什么read语句那里，变量“name”的前面不用加上“$”来标识这是一个变量啊？

varible doesn't need $ in front of. Only when you reference it...
