Re: [dsdp-tm-dev] Avoid output from before a command was executed (Re: Advice reg. including RSE...)
|
Note that the existing
RemoteCommandShellOperation
Class has some logic for ignoring initial output (and associating commands with their respective output).
The current implementation of the class has some issues, e.g.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=279837#c6
But you might still find it helpful looking at the code and trying it out in your scenario.
Thanks
Martin

Ok, many thanks!
