I want to do a large disk transfer, which slows down responsiveness of my system.
What I want is a Unix command that will only run the command after I have been idle at the console for a few minutes. And if I come back half way in, it will suspend the job. Until I walk away from my computer.
Is there such a command, or software package?
[edit: The key part of this question is how to determine if there is console activity, to automatically suspend.]
