(2) case案例
case $1 in 1) echo "安装apache" ;; 2) echo "安装mysql" ;; 3) echo "安装php" ;; 4) echo "整合LAMP" ;; *) echo "please enter Number1|2|3|" esac |
read -p "please enter Number:" number case $number in 1) echo -e "\033[36m安装apache\033[0m" ;; 2) echo -e "\033[36m安装mysql\033[0m" ;; 3) echo -e "\033[36m安装php\033[0m" ;; 4) echo -e "\033[36mplease enter number $0|1|2|3|help\033[0m" ;; *) echo "please enter Number1|2|3|" esac |
小结：
case语句中的变量，可以作为脚本的第一个参数传入，也可以通过read -p 通过键盘输入参数
selece语句
语法：
select i in （表达式）
do
语句
done
案例：
PS3="please enter select menu:" select i in install_apache install_php install_mysql quit do case $i in install_apache) echo "安装apache" ;; install_php) echo "安装php" ;; install_mysql) echo "安装mysql" ;; quit) echo "已退出安装" exit 0 ;; *) echo "please enter menu $0 install_apache|install_php|install_mysql" ;; esac done |
注释： (1) select语句和case语句可以嵌套使用 (2) select作为选择菜单，case接收到选择结果后，去执行出结果 |
