lucid
A simple mock-application that can be used by other programs that work with child processes.
lucid
is similar to sleep
, but has a few additional features that can be helpful
when debugging applications that spawn subprocesses.
Demo
Introduction
Applications or scripts that handle child processes need to deal with a lot of different scenarios.
There are really 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 just 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
There are also processes that choose to daemonize themselves immediately:
lucid 10 --daemon
Many processes print a lot on standard output:
lucid 10 --verbose
While some others might generate error messages:
lucid 10 --stderr --verbose
Usage
