最近在学习写shell脚本，在练习if while等流程控制时，突然它们的死循环写法是怎么样的？经过百度与亲测记录如下：

for死循环

#! /bin/bashfor ((;;));do        date        sleep 1done

while死循环

#! /bin/bashwhile :do        date        sleep 1done

#! /bin/bashwhile ((1))do        date        sleep 1done

#! /bin/bashwhile [[ 1 ]]do        date        sleep 1done

#! /bin/bashwhile [ 1 ]do        date        sleep 1done

#! /bin/bashwhile truedo        date        sleep 1done

#! /bin/bashwhile [[ "1" == "1" ]]do        date        sleep 1done

#! /bin/bashwhile test "1" = "1"do        date        sleep 1done

#! /bin/bashwhile [ TRUE ]do        date        sleep 1done
