 ### Options
 
 ```
       --attach[=false]: If true, wait for the Pod to start running, and then attach to the Pod as if 'kubectl attach ...' were called.  Default false, unless '-i/--interactive' is set, in which case the default is true.
+      --command[=false]: If true and extra arguments are present, use them as the 'command' field in the container, rather than the 'args' field which is the default.
       --dry-run[=false]: If true, only print the object that would be sent, without sending it.
       --generator="": The name of the API generator to use.  Default is 'run/v1' if --restart=Always, otherwise the default is 'run-pod/v1'.
