There is a some small Tk application (let's call it "launcher") which has been made for starting another script (let's call it "rocket" :-) ). I mean I run this launcher, choose/set some parameters and press button "run". Then it creates some config file which is a kind of an input for rocket. Then it should run rocket... And here I've got a problem. I need to see the process of rocket running - if I start it manually from console I see a lot of logs. I tried to run it using exec:
if [catch {exec rocket} errMsg] {
puts "Exception: $errMsg"
exit
}But it seems rocket starts logging into it's own output or whatever - I can't see anything in the console. And I haven't found any way to redirect it somewhere else except files.
Who knows, how to drive the output flow of child process? Or maybe there is another way to resolve the initial task?
