The article recounts the story of Alejandro, who, while working on a significant Unix migration project during the 1990s, mistakenly executed a command that erased his entire system. After training for five weeks to migrate a payroll application from an old IBM mainframe to a new NCR Unix machine, Alejandro attempted to clean up by removing temporary files post-installation. Fatigue from an all-nighter led to a catastrophic command error, demonstrating how even skilled professionals can falter under pressure.
After an all-nighter, Alejandro mistakenly executed a command that wiped the entire system instead of just temporary files, illustrating how one small mistake can have massive repercussions.
He recounted how the command he entered, thinking it would only delete temporary files, resulted in irretrievable data loss due to fatigue and misdirection.
