you don't have to write entire output of the shell to the file,
all shell commands supports output redirection to file/linux utilities
such as grep/etc. [1],

also in "script mode" printed limited MOTD (without welcome message)
if it still doesn't work for you, please file RFE (though i'm not sure it will 
make to 3.3)

[1] list snapshots --vm-identifier aaa > snapshots.txt

this is done for create "visual" isolation between bash and ovirt shells,
not sure i understand how it related to the told above, but if you find it
usable, i don't mind.

I actually didn't know that (just starting to use rhevm-shell)...this will
prove very helpful!

currently there is no "user-friendly" way to disable it,
can you elaborate please why do you need that?

Re: [Users] Disable MOTD on shell login

[Christian Hernandez]

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.
