Converting JSON pretty print to one line

Question

I have a command that I run and it gives an output like below:

{
\"endpointApplications\": {
    \"App_Name\": {
        \"connectionState\": \"Disconnected\",
          


        

Answer 1

jq or any other json aware tool is best suited for json file manipulation.However here is awk based solution.

awk -v RS= '{$1=$1}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 jq and have no chance to get them installed due to some reasons.
