shell实现菜单选择的两种方法

命令太长, 每次输入太麻烦, 搞了个shell菜单

#!/bin/bash#menu.shsource ~/.bashrcecho "----------------------------------"echo "please enter your choise:"echo "(0) mongotest"echo "(1) mongomaster"echo "(2) mongozwt179"echo "(3) mongobjsc115"echo "(4) mongobjsc102"echo "(9) Exit Menu"echo "----------------------------------"read inputcase $input in    0)    echo mongotest    sleep 1    mongotest;;    1)    echo mongomaster    sleep 1    mongomaster;;    2)    echo mongozwt179    sleep 1    mongozwt179;;    3)    echo mongobjsc115    sleep 1    mongobjsc115;;    4)    echo mongobjsc102    sleep 1    mongobjsc102;;    9)    exit;;esac

另一种是用select实现

#!/bin/bash#menu2.shecho "选择要连接的mongo数据库?"select var in mongobjsc102  mongobjsc115 mongozwt179 mongomaster;do    breakdoneecho "You have selected $var"
