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
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/bashcontent_url_new="https://hot1.example.com/"enable_feature1_new="true"enable_feature2_new="true"
config/mode2.sh
#!bin/bashcontent_url_new="https://hot2.example.com/"enable_feature1_new="false"enable_feature2_new="false"
main.sh
#!bin/bashif [ "$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 0ficase $1 inmode1) ????. config/mode1.sh;;mode2) ????. config/mode2.sh;;*) ???echo "Usage: sh main.sh [mode1|mode2]" ???exit;esac# 如果要修改的内容在文档中唯一,可以做全局修改content_url_old=$(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 mode1sh main.sh mode2
其他方案
- shell中替换json中指定的值 - 矮子爬楼梯 - 博客园
sh ??sed -i ?‘s/\("enable_feature1":"\).*/\1‘"$enable_feature1_to"‘",/g‘ ??example.json
