Unix shell design [was Re: Yes, Unix can do batch renames - Re: Unix handles file extensions "very poorly"?]

On the other hand VMS was/is trying to maintain a reputation of 24x365 and M$ was reboot often and keep the reset switch on the front of the machine. To have a machine that can do 24x365 you need good hardware and all along there were PCs up to the task but the OSs common were not so robust. From my perspecive at one time I had the luck of running VMS, One of the sorta unix (on pC) servers and NT4.51, VMS the biggest job was keeping the power supplied to the box and occasion new product additions, The unix PC was fairly stable but would suffer from disk and IO issues, the NT3.51 box was same hardware and added BSOD and memory leaks requiring reboots every week or application hangs never minding keeping at it to insure security. Also the VMS machine I could develop and deploy often without neededing to write a line of compiled code as DCL was usually more than enough.
