[9fans] Backgrounding a task

[newton688@gmail.com (Chris McGee)]

Thanks,

I was thinking more about the case where I didn't know ahead of time that the command would take a long time. I have a sequence of steps I do in Unix to background the task using job control in the shell. I wasn't sure if there is some kind of plan 9 equivalent to the workflow, even if it is done in a different way.

So far, it looks like the closest equivalent is to draw a new window and inherit the namespace of the original one by reading the namespace from the proc. I wonder if there could be a Rio gesture to draw a new window inheriting the namespace of the window I pick by clicking.

It's almost as if I had run it with '&' in the first place. I can then run other commands in the same working directory, environment and shell history.

Initially I thought, that you just drag that window to a corner somewhere and let it complete. But, if I draw a new window it won't be in the same working directory, have the same environment and namespace. Maybe there is a way to create a window that inherits these from an existing process?
