If I may interject....
Disabling the MOTD makes it easier to script...let's say if I want to get a list of VMs' snapshots and out them in a for loop...I would have to write the output of the rhevm-shell to a file; parse that file (oh BTW there are ^[[H and ^[[2 in that file...just to make things more interesteing); then run it through my loop - and then pass that into rhevm-shell...repeating the process. Also it doesn't help that rhevm-shell does a "clear" of the screen when it runs (can I turn that off too?)
I would have to do that for every command.
I don't mind having an MOTD...just wished there was an option to turn it off
In short: It makes it easier to script and automate tasks.
