Shell脚本练习

Shell实现输入数组，排序

read -a arr
echo "input arr ("${arr[@]}")"

for ((i=0;i<${#arr[@]};i++)) do
        for ((j=i+1;j<${#arr[@]};j++)) do
                if (( ${arr[j]}<${arr[i]} ))
                then
                        let temp=${arr[j]}
                        arr[j]=${arr[i]}
                        arr[i]=${temp}
                fi
        done
done;
echo "sorted arr ("${arr[@]}")"
