I want to "wrap" a process around another to catch
stderr messages when they occur.
I'm using Compass and I have to have a terminal open and see if there is something wrong. My plan is to use terminal-notifier tool to send myself OSX notifications so I notice an error happened. Then I don't have to keep terminal open on my screen all the time.
Imagine I have all this notification mechanism under a shell script named
compass-error.sh which will send a notification when you call it. Now I want to run
compass watch with my main process and watch for
stderr to fire
compass-error.sh. How do I do it?
