在BASH多维数组 [英] multi-dimensional arrays in BASH

问题描述

我打算一个脚本来管理Linux系统的一些作品和我在决定点，如果我想使用的庆典或的蟒蛇。

I am planning a script to manage some pieces of my Linux systems and am at the point of deciding if I want to use bash or python.

我想preFER做到这一点作为一个Bash脚本仅仅是因为命令是比较容易的，但真正的决定因素是配置。我需要能够存储在配置文件中的多维阵列告诉脚本做什么用本身。存储简单的键=在配置文件值对是使用bash很容易，但我能想到的唯一的方式做一个多维数组是一个两层解析引擎，像

I would prefer to do this as a Bash script simply because the commands are easier, but the real deciding factor is configuration. I need to be able to store a multi-dimensional array in the configuration file to tell the script what to do with itself. Storing simple key=value pairs in config files is easy enough with bash, but the only way I can think of to do a multi-dimensional array is a two layer parsing engine, something like

array=&d1|v1;v2;v3&d2|v1;v2;v3

但马歇尔/解组code能拿是熊和它远离用户友好的下一个可怜虫有管理这一点。如果我不能在bash做到这一点很容易，我会简单地写了CONFIGS一个XML文件，并在Python写剧本。

but the marshall/unmarshall code could get to be a bear and its far from user friendly for the next poor sap that has to administer this. If i can't do this easily in bash i will simply write the configs to an xml file and write the script in python.

有没有一种简单的方法在bash做到这一点？

Is there an easy way to do this in bash?

感谢大家。

推荐答案

击不支持也不多维数组，无论是哈希，似乎你想要一个哈希值是数组。该解决方案是不是很漂亮，有一个xml文件的解决方案应该会更好：

Bash does not support neither multidimensional arrays, neither hashes, and it seems that you want a hash that values are arrays. This solution is not very beautiful, a solution with an xml file should be better :

array=('d1=(v1 v2 v3)' 'd2=(v1 v2 v3)')
for elt in "${array[@]}";do eval $elt;done
echo "d1 ${#d1[@]} ${d1[@]}"
echo "d2 ${#d2[@]} ${d2[@]}"
