【问题描述】：
首先，对不起我的英语，我是法国人。
我正在编写一个脚本，该脚本从 M3U 文件中检索标签和链接，以将它们存储到变量中。 M3U：
#EXTM3U
#EXTINF:-1 tvg-id="TFX.fr" tvg-name="TFX" tvg-country="FR;AD;BE;LU;MC;CH" tvg-language="French" tvg-logo="http://www.exemple.com/image.jpg" group-title="",TFX (720p)
https://tfx-hls-live-ssl.tf1.fr/tfx/1/hls/live_2328.m3u8
脚本：
#!/bin/bash
tags='#EXTINF:-1 tvg-id="TFX.fr" tvg-name="TFX" tvg-country="FR;AD;BE;LU;MC;CH" tvg-language="French" tvg-logo="http://www.exemple.com/image.jpg" group-title="Fiction",TFX (720p)'
get_chno="$(echo "$tags" | grep -o 'tvg-chno="[^"]*' | cut -d '"' -f2)"
get_id="$(echo "$tags" | grep -o 'tvg-id="[^"]*' | cut -d '"' -f2)"
get_logo="$(echo "$tags" | grep -o 'tvg-logo="[^"]*' | cut -d '"' -f2)"
get_grp_title="$(echo "$tags" | grep -o 'group-title="[^"]*' | cut -d '"' -f2)"
get_title="$(echo "$tags" | grep -o ',[^*]*' | cut -d ',' -f2)"
get_name="$(echo "$tags" | grep -o 'tvg-name="[^"]*' | cut -d '"' -f2)"
get_country="$(echo "$tags" | grep -o 'tvg-country="[^"]*' | cut -d '"' -f2)"
get_language="$(echo "$tags" | grep -o 'tvg-language="[^"]*' | cut -d '"' -f2)"
echo -e "chno:\n $get_chno"
echo -e "id:\n $get_id"
echo -e "logo:\n $get_logo"
echo -e "grp 1:\n $get_grp_title"
echo -e "title:\n $get_title"
echo -e "name:\n $get_name"
echo -e "country:\n $get_country"
echo -e "lang:\n $get_language"
我想将这些变量存储在一个 json 文件中。 此 json 将用于重建另一个播放列表。
#EXTM3U
#EXTINF:-1 tvg-id="TFX.fr" tvg-name="TFX" tvg-country="FR;AD;BE;LU;MC;CH" tvg-language="French" tvg-logo="http://www.exemple.com/image.jpg" group-title="",TFX (720p)
https://tfx-hls-live-ssl.tf1.fr/tfx/1/hls/live_2328.m3u8
#EXTINF:-1 tvg-id="TFX.fr" tvg-name="TFX" tvg-country="FR;AD;BE;LU;MC;CH" tvg-language="French" tvg-logo="http://127.0.0.1/img/image.jpg" group-title="",TFX (local)
http://127.0.0.1:1234/tfx/live.m3u8
包含多个数组和多个对象的文件。

第一个问题：它是一个糟糕的 json 吗？
要添加或修改这个文件，脚本必须有入口号（我想，如果你有其他想法，我很感兴趣......）
cat File.json | jq '.Channels | to_entries[]'
输出：
{
"key": 0,
"value": {
"name": "TFX",
"old_name": "NT1",
第二个问题： 如何使用“名称”的值获取值键（这种情况下为 0），以便在之后存储到变量中？ （避免重复）
key_="$(cat file.json | jq ????????? search="name": "$get_name" ???? .key)"
echo $key_
"0"
key_2="$(cat file.json | jq ????????? search="name": "$get_url" ???? .key)"
echo $key_2
"0"
if [[ $key_ == $key_2 ]]; then
Chan_Name="$(cat $1 | jq '.Channels[$key_].name)"
Echo $Chan_Name
"TFX"
jq '.[] ????? += {???? , ??? }' file.json | sponge file.json
fi
最后一个问题（最重要的）： 当脚本不知道对象/数组的键的任何值时，如何查找和修改这些 f*** 对象？！
我已经找了 2 天了，我的大脑是液体。
谢谢。 :)
编辑 1：
我找到了替换值的部分解决方案：
{
"name": "TFX",
"old_name": "NT1",
"logo": "http://www.exemple.com/image.jpg",
"category": "Fiction",
与：
cat file.json | jq -C '(.Channels[] | select(.name=="TFX").category="test")'
输出：
{
"name": "TFX",
"old_name": "NT1",
"logo": "http://www.exemple.com/image.jpg",
"category": "test",
"urls": {
但是 "{"Channels": [" 不见了。 ：/
