作为列表的变量

Question

我在Solaris 2.10上使用ksh“版本M-11/16/88i”。

我在列表中遇到了一些问题。

第一个例子工程，我想：

#!/bin/ksh 
for i in ONE "one is 1" TWO "two is 2" THREE three 
do 
echo $i 
done 

的这个输出是：

> ./mytest.ksh 
ONE 
one is 1 
TWO 
two is 2 
THREE 
three 
> 

但是，如果我的代码更改为类似这样：

#!/bin/ksh 
MYVAR="ONE \"one is 1\" TWO \"two is 2\" THREE three" 
echo "MYVAR=$MYVAR" 
for i in $MYVAR 
do 
echo $i 
done 

那么输出是：

> ./mytest.ksh 
MYVAR=ONE "one is 1" TWO "two is 2" THREE three 
ONE 
"one 
is 
1" 
TWO 
"two 
is 
2" 
THREE 
three 
> 

我该如何将值保存在变量MYVAR中，以便循环FOR能正确使用它？ 谢谢。

Answer 1

这里是一个办法做到这一点：

#!/bin/sh 
MYVAR="ONE \"one is 1\", TWO \"two is 2\", THREE three" 
export IFS=","; 
echo "MYVAR=$MYVAR" 
for i in $MYVAR 
do 
echo $i 
done 

Answer 2

尝试在echoeing喜欢引用：

MYVAR="ONE \"one is 1\" TWO \"two is 2\" THREE three" 
echo "MYVAR=$MYVAR" 
for i in "$MYVAR" 
     ^ ^
do 
    echo $i 
done  
Output: 
MYVAR=ONE "one is 1" TWO "two is 2" THREE three                   
ONE "one is 1" TWO "two is 2" THREE three
