shell腳本之死循環寫法

最近在學習寫shell腳本，在練習if while等流程控制時，突然它們的死循環寫法是怎麼樣的？經過百度與親測記錄如下：

for死循環

#! /bin/bash

for ((;;));do
        date
        sleep 1
done

while死循環

#! /bin/bash

while :
do
        date
        sleep 1
done

#! /bin/bash

while ((1))
do
        date
        sleep 1
done

#! /bin/bash

while [[ 1 ]]
do
        date
        sleep 1
done

#! /bin/bash

while [ 1 ]
do
        date
        sleep 1
done

#! /bin/bash

while true
do
        date
        sleep 1
done

#! /bin/bash

while [[ "1" == "1" ]]
do
        date
        sleep 1
done

#! /bin/bash

while test "1" = "1"
do
        date
        sleep 1
done

#! /bin/bash

while [ TRUE ]
do
        date
        sleep 1
done
