SHELL脚本

1、冒泡法排序

做运算 ((n-1))

取变量数组值 ${arry[$i]}、${arry[$((i+1))]}

#!/bin/bash
arry=(27 5 13 8 9 5 10 6)
n=${#arry[@]}
for ((i=0;i<$n;i++))
do
        for((j=0;j<$((n-i-1));j++))
        do
                if [ ${arry[$j]} -gt ${arry[$((j+1))]} ]; then
                        temp=${arry[j+1]}
                        arry[$((j+1))]=${arry[$j]}
                        arry[$j]=$temp
                fi
        done
done
echo ${arry[@]}
