这是有关如何将“不可解析的”输出解析为json或易于消费为json的内容的问题。这只是琐碎事情的“一点”，所以我想知道，原则上您如何解决这些问题，这不仅与这个特定示例有关。但是例子：
我们有此命令，它显示有关音频输入的数据：
pacmd list-sink-inputs
它打印出这样的内容：
2 sink input(s) available.
index: 144

native-protocol.version = "32"
application.process.id = "1543"
application.process.user = "mmucha"
application.process.host = "vbDesktop"
application.process.binary = "mplayer"
application.language = "C"
window.x11.display = ":0"
application.process.machine_id = "720184179caa46f0a3ce25156642f7a0"
application.process.session_id = "2"
module-stream-restore.id = "sink-input-by-application-name:MPlayer"

module: 13
client: 251 <MPlayer>
properties:
media.name = "Trombone Shorty At Age 13 - 2nd Line-k9YUi3UhEPQ.webm"
application.name = "MPlayer"
native-protocol.peer = "UNIX socket client"
native-protocol.version = "32"
application.process.id = "2831"
application.process.user = "mmucha"
application.process.host = "vbDesktop"
application.process.binary = "mplayer"
application.language = "C"
window.x11.display = ":0"
application.process.machine_id = "720184179caa46f0a3ce25156642f7a0"
application.process.session_id = "2"
module-stream-restore.id = "sink-input-by-application-name:MPlayer"
非常好。但是我们不想向用户显示所有这些信息，我们只想以某种合理的格式显示索引（输入的ID），application.process.id，application.name和media.name。最好将它解析为json，但是即使我以某种方式对其进行了预处理，jq也远远超出了我的能力并且非常复杂。我尝试了使用jq，使用正则表达式或不使用正则表达式的多种方法，但无法完成。而且我想我们不能依赖所有字段的顺序或存在。我能够“完成”工作，但是它很杂乱，效率低下，即媒体名称或应用程序名称中不应包含分号。不能接受的解决方案，但这是我唯一可以解决的问题。
不正确的解决方案：
cat exampleOf2Inputs |
grep -e "index: \|application.process.id = \|application.name = \|media.name = " |
sed "s/^[ \t]*//;s/^\([^=]*\) = /\1: /" |
tr "\n" ";" |
sed "s/$/\n/;s/index:/\nindex:/g" |
tail -n +2 |
while read A; do
index=$(echo $A|sed "s/^index: \([0-9]*\).*/\1/");
pid=$(echo $A|sed 's/^.*application\.process\.id: \"\([0-9]*\)\".*$/\1/');
appname=$(echo $A|sed 's/^.*application\.name: \"\([^;]*\)\".*$/\1/');
medianame=$(echo $A|sed 's/^.*media\.name: \"\([^;]*\)\".*$/\"\1\"/');
echo "pid=$pid index=$index appname=$appname medianame=$medianame";
done
〜我刺破了有趣的部分，用分号替换了换行符，分割为多行，并使用sed多次提取了数据。疯狂。
这里输出是：
pid=1543 index=144 appname=MPlayer medianame="UNREAL! Tetris Theme on Violin and Guitar-TnDIRr9C83w.webm"
pid=2831 index=145 appname=MPlayer medianame="Trombone Shorty At Age 13 - 2nd Line-k9YUi3UhEPQ.webm"
可以轻松转换为任何格式，但是问题是关于json的，所以要：
[
{
"pid": 1543,
"index": 144,
"appname": "MPlayer",
"medianame": "UNREAL! Tetris Theme on Violin and Guitar-TnDIRr9C83w.webm"
},
{
"pid": 2831,
"index": 145,
"appname": "MPlayer",
"medianame": "Trombone Shorty At Age 13 - 2nd Line-k9YUi3UhEPQ.webm"
}
]
现在，我想看看这些事情是如何正确完成的。
