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.

I don't want to kill it. I'll just Ctrl-Z and bg to put it into the background using the shell. 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. >>> >>> Is there an equivalent to this workflow in Plan 9? >>> >>> I realize that the whole job control system dates back to old single session terminals, which isn't a problem with Rio where you can draw new windows at will. 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? >>> >>> Chris -------------- next part -------------- An HTML attachment was scrubbed... URL:
