Converting JSON pretty print to one line
提问by h.b
I have a command that I run and it gives an output like below:
我有一个我运行的命令，它提供如下输出：
{
"endpointApplications": {
"App_Name": {
"connectionState": "Disconnected",
"connectionTime": "No connection was established",
"linkAttributes": {
"ackSettings": {
"dataAckEnabled": "true",
"dataAckTimeout": "5000",
"dataNakRetryLimit": "0",
"retransmitDelay": "500"
},
"keepAliveSettings": {
"keepAliveAckTimeout": "5000",
"keepAliveInterval": "30000"
},
"logTraffic": "false",
"port": "9999",
"role": "server"
},
"protocol": "snmp"
}
},
"queueStats": {}
}
I would need the output to be in one line like below:
我需要输出在一行中，如下所示：
{"endpointApplications": {"app_name": {"connectionState": "Disconnected","connectionTime": "No connection was established","linkAttributes": {"ackSettings":{"dataAckEnabled": "true","dataAckTimeout": "5000","dataNakRetryLimit": "0","retransmitDelay": "500"},"keepAliveSettings":{"keepAliveAckTimeout": "5000","keepAliveInterval": "30000"},"logTraffic": "false","port": "9999","role": "server"},"protocol": "snmp"}},"queueStats":{}}
I tried using awk and sed combining different parameters but I can't get to work without losing the JSON format.
我尝试使用 awk 和 sed 结合不同的参数，但我无法在不丢失 JSON 格式的情况下开始工作。

jqor any other jsonaware tool is best suited for json file manipulation.However here is awkbased solution.
jq或任何其他json感知工具最适合 json 文件操作。然而，这里是awk基于解决方案。
awk -v RS= '{=}1' input.json
{ "endpointApplications": { "App_Name": { "connectionState": "Disconnected", "connectionTime": "No connection was established", "linkAttributes": { "ackSettings": { "dataAckEnabled": "true", "dataAckTimeout": "5000", "dataNakRetryLimit": "0", "retransmitDelay": "500" }, "keepAliveSettings": { "keepAliveAckTimeout": "5000", "keepAliveInterval": "30000" }, "logTraffic": "false", "port": "9999", "role": "server" }, "protocol": "snmp" } }, "queueStats": {} }
Note: This solution is mainly for the legacy systems not having tools like jqand have no chance to get them installed due to some reasons.
注意：此解决方案主要针对没有此类工具jq且由于某些原因没有机会安装它们的旧系统。

You should use jqfor stuff like that:
你应该使用jq来处理这样的事情：
jq -c . input.txt
An alternative quick a dirty solution would be to use sed& tr:
另一种快速肮脏的解决方案是使用sed& tr：
sed -e 's/^ *//' < input.txt | tr -d '\n'
although I would recommend using jqwhich is designed for manipulating JSON. jqis like sedfor JSON. Manipulating JSON textually with sed/awk/etc is not guaranteed to produce semantically equivalent JSON.
尽管我建议使用jqwhich 是为操作 JSON 而设计的。jq就像sedJSON。使用sed/ awk/etc 以文本方式操作 JSON不能保证生成语义等效的 JSON。
