Consider about the option and whether it is possible to fix the host for the command

[zshamrock]

And whether it really makes sense.

I.e. if there is the specific command which only could be run against specific host, so then the host could be specified as part of the command.

Although the open question as the format of the run is the following: run <host name> <command>, and if the host name is fixed, what value should be provided for the host name? _ (like in various languages where the value is not important)? Or change the order of the host name and command, so the run command becomes: run <command> <host name>, although the later is probably not convenient, as it is handy to be able to run multiple commands in a row for the host name, so it becomes easier to do.
