What is the best way? Or at least... an easily managed one?
I am routinely creating shell and python scripts that need to always be running in the background.
Any recommendations on packages that simplify this? In the past I would stick a shell script in cron to check for the running process, but this feels like a hack. I recently read about a program called Angel, which is written in Haskell that does this, but this seems like a common use that would be built in to the OS somewhere.
edit: What tool would reduce the time I spend on this activity and result in something both easily maintainable and quickly deployable to new servers?
