I typically use about 10 windows in gnu screen and am constantly customizing my .bashrc. I would like to be able to source .bashrc across screen windows with a one-liner. Can I broadcast a command to all my screen windows without detaching my session, running the command (in this case, sourcing the profile) and re-attaching to the screen session? I use Mac OS 10.8.
I believe this solution will also work for what I want to do, but curious if there is a more concise way.
