Exit code 0 is a lie: 7 ways my unattended automation silently did nothing
In this article, the author recounts seven scenarios where their unattended automation scripts returned exit code 0 but actually did nothing. These include cases where commands produced no output, variables were unset, or conditional logic silently skipped the intended actions. The author emphasizes that a zero exit code does not guarantee success, as many tools and scripts can exit cleanly even when they fail to perform their intended function. The article is a personal narrative, likely drawing from the author's own experiences with cron jobs or scheduled tasks. The key takeaway is that relying solely on exit codes can lead to silent failures, and developers should implement additional checks or logging to ensure automation actually completes its tasks. The source text is a DEV Community post, and the content is anecdotal rather than a formal study, but it highlights a common pitfall in automation.
Exit code 0 can mask silent failures in automation, misleading developers into thinking tasks succeeded.
