I am trying to update ES as a rolling upgrade for the 1st time. ( I am a new user) and I am reading the documentation and I come across this syntax that is another representation of JSON:
> PUT /\_cluster/settings
> {
> "transient": {
> "cluster.routing.allocation.enable": "none"
> }
> }'
Source: [Rolling upgrade | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/rolling-upgrades.html)
I thought it was shorthand notation for the following:
> curl -POST localhost:9200/elk\_cluser\_main/settings -d '
> {
> "transient": {
> "cluster.routing.allocation.enable": "none"
> }
> }'
Obviously I am wrong. Can someone explain this shorthand notation?

It's just;
```auto
curl -XPUT host:9200/_cluster/settings -d '{
"transient": {
"cluster.routing.allocation.enable": "none"
}
}'
```
That syntax is [Sense](https://www.elastic.co/guide/en/sense/current/index.html) formatted.

Should have clicked on that sense hyperlink in the docs. Thanks!
