Google. There are also some sites that have commands listed categorically.

Old man and LINUX

by Ken Jones

Folks, I have always wondered at my ability to keep the myriad of LINUX instructions in my head. What would I do if I were to start losing them? Is there a tool to search for recall? Is there any way to go backwards in LINUX command land? If I were to remember that there is a command that will print on standard output the contents of a file in txt characters, but could not for the life of me remember 'more'. Where would I go for help (other than sending a email to this list serve)? All the command dictionaries I have are alphabetic. Ken Jones (the elder)

Yeah, it was somewhere between 2-3' of snow. It even has it's own Wikipedia page: http://en.wikipedia.org/wiki/April_Fool's_Day_Blizzard And it occurred to me right before finding that page that it was 1997, not 1996. :( I can remember watching the snow from Fuller Apartments, and I wasn't living there in April 1996.

Grumble. I remember back in either late '92 when I was a 16 year old commuting Mass Academy student and I came back to my car, in my assigned WPI parking lot (across the street from the end of the sports field) and found a parking ticket because apparently the lot was supposed to be clear for snow removal. I'm not sure what channel I was supposed to get a notification about this from. They certainly didn't put up a sign. Classes were most definitely not canceled. The lot was full, so obviously no one else had gotten the message either. Oh, and the ticket was underneath a perfectly even and undisturbed layer of snow, so I'd obviously gotten it before any snow had fallen at all. I'll always remember that as my first parking ticket. Grumble, mumble and additional disgruntled noises. On Tue, 2011-01-11 at 17:46 -0500, Theo Van Dinter wrote: > Woh!

Had a few delayed openings/early closings while I was there. I think maybe one full day off from a snowstorm. On Tue, Jan 11, 2011 at 5:46 PM, Theo Van Dinter <felicity(a)kluge.net> wrote: > Woh!

Woh! I remember back in '96 when we were all amazed that they closed the campus for the first time in something like 20 years. Is this the first time since then?
