请教这个脚本怎么运行不了？

[xiaoyaofawai]

#!/bin/bash
for var in A B C
do
　echo "var is $var"
done
echo "You have selected $var"

运行后：
./first: line 4: 　echo: command not found
./first: line 4: 　echo: command not found
./first: line 4: 　echo: command not found
You have selected C

还有if []
then
fi
也运行不了

恳请指教！！

你的 [　echo "var is $var" ]这儿,在echo前面有一个中文字符的空格!!

请用tab或英文空格

[joseneo]

echo "var is " $var

echo "var is " $var 和echo "var is $var“应该一样的吧，单引号才会有区别吧？

真仔细啊……
