在 solaris 中读入无限循环

Question

# cat test.sh
#!/usr/xpg4/bin/sh
while true; do
read -p "do you want to continue (Y/N) ?" yn
    case $yn in
        [Yy]* ) echo " Yes "; 
        [Nn]* ) echo " No "; exit;;
        * ) echo "Please answer yes or no.";;
    esac
done
echo "execution completed..."

上面的测试脚本进入了无限循环，但如果我使用 /usr/bin/bash.

它工作正常

如何制作此脚本以使其在 #!/usr/xpg4/bin/sh 中运行？请帮助我是 shell 脚本的新手，对 POSIX 和所有东西一无所知。

Answer 1

来自 www.shellcheck.net：In POSIX sh, read -p is undefined.

替换

read -p "do you want to continue (Y/N) ?" yn

来自

printf "%s" "do you want to continue (Y/N) ?"
read yn
