Use: "stream [user|local|public|:HASHTAG]", |

28 |
The stream command stays connected to the server and listen to a stream of |
|
29 |
events (user, local or federated). |
|
30 |
It can also get a hashtag-based stream if the keyword or prefixed with |
|
31 |
':' or '#'.`, |
|
32 |
Example: ` madonctl stream # User timeline stream |
|
33 |
madonctl stream local # Local timeline stream |
|
34 |
madonctl stream public # Public timeline stream |
|
35 |
madonctl stream :mastodon # Hashtag |
|
36 |
madonctl stream #madonctl`, |
