About fifteen years back I wrote a shell script which runs in the background and which is supposed to send an email to the administrator with the log file , every time it ends up with error. The trouble was, it was an infinite loop( being a background process!) and there was some error .I forgot to tell the code to end , in case there was an error.Very dutifully, the program clogged up the company mail server completely with thousands of mails with error logs over the weekend ,no emails coming or going out and one very angry administrator.
