I'm no sysadmin, but I've created/worked on some extremely large systems (thousands of machines) and nobody running anything in production environments would ever use screen for keeping things running. It's just not designed for that. It has horrendous potential scenarios for disaster by people pressing the wrong keys. It doesn't deal with log rotation or storage or timestamping. It doesn't deal with restarting failed processes. It's designed for interactive use. It's in no way designed as a secure keep-alive system for daemons.
Compare that to: http://smarden.org/runit/benefits.html I think if you hired a sysadmin (at least one worth what you pay him) he would replace your "screen" based system in a flash. On the other hand, I do use screen for everything else, and have it constantly logged in doing "tail -F" on all my logs, so I can instantly see what's going on in real time and pause and scroll back those logs if I need to. I just don't use it for keeping daemons running. On Wed, Oct 17, 2012 at 12:59 PM, Jimb Esser <[email protected]> wrote: > Is there a problem with running in "screen"?
