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

You should use jq for stuff like that:

jq -c . input.txt

An alternative quick a dirty solution would be to use sed & tr:

sed -e 's/^ *//' < input.txt | tr -d '\n'

although I would recommend using jq which is designed for manipulating JSON. jq is like sed for JSON. Manipulating JSON textually with sed/awk/etc is not guaranteed to produce semantically equivalent JSON.
