A simple mock-application that can be used by other programs that spawn subprocesses.
lucid is similar to sleep, but has a few additional features that can be helpful
when debugging applications that spawn subprocesses.
Applications or scripts that handle child processes need to handle a lot of different scenarios.
There are very simple processes that successfully terminate after a short period of time:
lucid 2
Others also finish after some time but fail with a non-zero exit code:
lucid 3 --exit-code=1
Some processes run forever (but can be terminated via SIGINT or SIGTERM)
lucid
Others refuse to handle termination signals properly and just ignore them:
lucid 10 --no-interrupt
Many processes output a lot on standard output:
lucid 10 --verbose
Others generate a lot of error messages:
lucid 10 --stderr --verbose
``` USAGE: lucid [OPTIONS] [duration]
