【shell】sh實現 在變量名中引用變量

變量名中引用變量的值

name="zhangsan lisi wangwu"

zhangsan_age="109"
lisi_age="98"
wangwu_age="74"

for i in ${name};do
        echo "name=${i}"
        age=${i}_age
        echo "${i}的年齡：${!age}"
done

 

　　運行結果

　　

 

 

 

多層引用變量值

name="zhangsan lisi wangwu"

zhangsan_age="109"
lisi_age="98"
wangwu_age="74"

health_109="衰老"
health_98="正常"
health_74="虛弱"



for i in ${name};do
        echo "name=${i}"
        age=${i}_age
        echo "${i}的年齡：${!age}"
        health=health_${!age}
        echo "${i}的身體狀況：${!health}"
done
