shell读取ini配置文件到字典里

测试文件test.ini内容为：

[mysection1] #我是注释
mytestkey1=myvalue1 #我是注释

[mysection2]
mytestkey2=myvalue2

[mysection3]
mytestkey3=myvalue3

shell脚本testr.sh代码：

#!/bin/bash

declare -A myini

while read string;
do

# 获取section标题
if [[ $string =~ .*\[[^]]+\].* ]]; then
    section=$(echo "$string" | grep -oP '\[.*\]' | sed 's/\[\|\]//g' | sed 's/^[[:space:]]*//;s/[[:space:]]*$//')
    echo $section
fi


# 获取section下的key-value
if [[ $string =~ .*=[^=]+ ]]; then
    key=$(echo "$string" | awk -F '=' '{print $1}' | sed 's/^[[:space:]]*//;s/[[:space:]]*$//' | sed 's/#.*//g')
    value=$(echo "$string" | awk -F '=' '{print $2}' | sed 's/^[[:space:]]*//;s/[[:space:]]*$//' | sed 's/#.*//g')
    #echo $section-  $key-  $value-
    myini[$section, $key]=$value

fi




done < test.ini


mykey="mytestkey2"
echo "-------------------r"
echo ${myini[mysection1, mytestkey1]}
echo ${myini[mysection2, $mykey]}

测试结果：

root@mypc:~# ./test.sh
mysection1
mysection2
mysection3
-------------------r
myvalue1
myvalue2
