【Shell】shell脚本修改json中某个字段的值

shell脚本修改json中某个字段的值

思路：通过awk来找到旧数据，然后用sed来替换旧数据https://download.csdn.net/download/ly1414725328/10744793

源码

config.json

{ "name": "the_name", "id": "132869", "content_url": "https://hot.example.com/", "enable_feature1": "true", "enable_feature2": "false" }

config/mode1.sh

#!bin/bash content_url_new="https://hot1.example.com/" enable_feature1_new="true" enable_feature2_new="true"

config/mode2.sh

#!bin/bash content_url_new="https://hot2.example.com/" enable_feature1_new="false" enable_feature2_new="false"

main.sh

#!bin/bash if [ "$1" != "mode1" -a "$1" != "mode2" ];then echo "tip:─┬─────── 您输入参数不对，请重试：" echo " │─────── 'mode1', 使用config/mode1.sh的配置" echo " └─────── 'mode2', 使用config/mode2.sh的配置" exit 0 fi case $1 in mode1) . config/mode1.sh ;; mode2) . config/mode2.sh ;; *) echo "Usage: sh main.sh [mode1|mode2]" exit; esac # 如果要修改的内容在文档中唯一，可以做全局修改 content_url_old=$(awk -F"\"" '/content_url/{print $4}' example.json) sed -e "s@$content_url_old@$content_url_new@g" -i example.json # 如果要修改的内容在文档中不唯一，就需要针对那一行做修改。（例如，这个例子中有两个布尔类型的值） enable_feature1_line=$(awk -F"\"" '/enable_feature1/{print NR}' example.json) # 记住行号 enable_feature1_old=$(awk -F"\"" '/enable_feature1/{print $4}' example.json) # 获取旧数据 sed -e "$enable_feature1_line s@$enable_feature1_old@$enable_feature1_new@" -i example.json # 替换所在行的老数据 enable_feature2_line=$(awk -F"\"" '/enable_feature2/{print NR}' example.json) # 记住行号 enable_feature2_old=$(awk -F"\"" '/enable_feature2/{print $4}' example.json) # 获取旧数据 sed -e "$enable_feature2_line s@$enable_feature2_old@$enable_feature2_new@" -i example.json # 替换所在行的老数据

运行

sh main.sh mode1 sh main.sh mode2
