在下面的脚本中——它会提示用户确认他们想要继续运行一个潜在的错误脚本——当用户Y
在提示处输入时——它将跳出case

循环。
#! /bin/bash
set -e
echo
echo "bad install start"
echo "-----------------------------------------"
while true; do

当n
输入的,脚本存在尽如人意。我想知道如何做到这一点,以便在Y
输入脚本时同时跳出 thecase
和while 块,但不会完全退出。我可以为占位符(“这里有什么??”)添加一些东西来做到这一点?

在用户输入“y”的情况下,您可以同时退出 while 和 case:
break [n]
Exit from within a for, while, until, or select loop. If n is
specified, break n levels. n must be ? 1. If n is greater than
the number of enclosing loops, all enclosing loops are exited.
The return value is 0 unless n is not greater than or equal to
1.
