-t TOKEN Slack access token
-c CHANNEL_NAME channel name
-u USERNAME username
-m MESSAGE message
-f IMAGE_HREF in case you dont want to impersonate an existing user, you can provide an arbitrary image href. Note that -r won't have any effect in that case.
-r use the user real name instead of its username.
