select $var in ${list[@]}
do
statements that can use $var
done在select执行时，会根据list数组给出选择菜单，用户选择后的结果保存在$var变量中，然后执行statements语句。执行完成后，再次给出菜单，等待用户选择。如果用户想跳出选择循环，需要在循环体中根据条件增加break语句。#!/bin/bash
fruits=(
"apple"
"pear"
"orange"
"watermelon"
)
echo "Please guess which fruit I like :"
select var in ${fruits[@]}
do
if [ $var = "apple" ]; then
echo "Congratulations, you are my good firend!"
break
else
echo "Try again!"
fi
