Re: Ah, pipes, pipes, pipes...
Indeed, that was the case. Wanna hear the worst part of it? A fellow US sysadmin taught out star DB dev that trick. That asshole (Hey Matt, I hope you're doing well these days, you scumbag!) used to log in while our junior sysadmins were executing scheduled changes, to perform other modifications sketchily arranged with the customer on the side. So if something would go bork, it'd be somebody elses' fault, instead of his. And we're talking ODM mods on AIX servers here, the equivalent of punching regedit commands on Windows...
This all ended when I demanded him to log off the server I was working on or else I would mark the change request as failed and expose him in front of the manglement.
