如何在Shell脚本中从数组中找到最大元素及其索引。我有一个数组
How can I find the maximum element and its index from an array in shell script. I have an array
a = [-2.2116565098 -2.1238242060 -2.1747941240 -2.3201010162 -2.3677779871 -1.8126464132 -2.1247209755 -2.1190930712 -2.3242384636 -2.1081702064];现在，我想在bash脚本中找到最大值及其索引。是否有类似Matlab的快捷方式
Now, I want to find the maximum as well as its index in bash script. Is there a shortcut like in Matlab we have
[C, I] = max(a);同样，我们如何拥有多维数组并获得最小值和最大值的索引和值元件。
Also, also how can we have multi-dimensional array and get the index and value of minimum and maximum element.
推荐答案$ x='-2.2116565098 -2.1238242060 -2.1747941240 -2.3201010162 -2.3677779871' $ IC=(`tr ' ' '\n' <<<$x | cat -n | sort -k2,2nr | head -n1`) $ I=${IC[0]} C=${IC[1]} $ echo $I $C 2 -2.1238242060
