巴什解析阵列从配置文件 [英] Bash Parse Arrays From Config File

问题描述

我需要包含在文件中为每个部分的数组：

I need to have an array for each "section" in the file containing:

[array0]
value1=asdf
value2=jkl

[array1]
value1=1234
value2=5678

我希望能够找回这样这些值：

I want to be able to retrieve these values like this:

echo ${array0[value1]}
echo ${array0[value2]}

echo ${array1[value1]}
echo ${array1[value2]}

这是如何做到这一点有什么想法？ （解释将是一个奖金）

Any thoughts on how to accomplish this? (Explanations would be a bonus)

我已经阅读这些anwsers但没有不正是我想要做的。

I've already read these anwsers but none do exactly what I want to do.

BASH解析从配置文件变量

推荐答案

在bash V4，使用关联数组，存储从配置文件作为实际bash的变量属性：

with bash v4, using associative arrays, store the properties from the config file as actual bash variables:

$ while read line; do 
    if [[ $line =~ ^"["(.+)"]"$ ]]; then 
        arrname=${BASH_REMATCH[1]}
        declare -A $arrname
    elif [[ $line =~ ^([_[:alpha:]][_[:alnum:]]*)"="(.*) ]]; then 
        declare ${arrname}[${BASH_REMATCH[1]}]="${BASH_REMATCH[2]}"
    fi
done < config.conf

$ echo ${array0[value1]}
asdf

$ echo ${array1[value2]}
5678

$ for i in "${!array0[@]}"; do echo "$i => ${array0[$i]}"; done
value1 => asdf
value2 => jkl

$ for i in "${!array1[@]}"; do echo "$i => ${array1[$i]}"; done
value1 => 1234
value2 => 5678
