Are there any words in the English language that use at least half of the alphabet without repeating any letters?

cat /usr/share/dict/words | egrep '^\w{13,}$' | egrep -iv '(\w).*\1'
This is the most straightforward approach: first regexp limits dictionary file to words with thirteen or more characters, second regexp discards any words that have a letter repeated. (Bonus challenge: Try doing it in a single regexp!)
Sample Output
# You'll just have to try it to find out!

P.S. Please don't put the answer in the comments. Let people figure it out and/or be surprised! :-)

the "cat blah | egrep " structure is always ugly to me. the following does exactly the same : egrep '^\w{13,}$' /usr/share/dict/words | egrep -iv '(\w).*\1'

You're right, snaguber, that does work and it saves four or five keystrokes plus an entire process. I find the superfluous cat helpful, even beautiful, when I'm working with pipelines, though, as it keeps the data flowing from left to right. Beauty is in the eye of the beholder, I suppose.

I am looking here for more such commands from here.

I really don't think there are such configurations of the alphabet, but I may also be wrong though. Much like AI Essay Writing Software: Pros and Cons though, I didn't think that a platform like this was possible either. So all in all then, I guess the alphabet may surprise me too.

You're correct, snaguber, that takes care of business and it saves four or five keystrokes in addition to a whole cycle. I find the pointless feline supportive, even wonderful, while I'm working with pipelines, however, as it keeps the information moving from left to right. you have a decent bearing, it's not difficult to go for it. Obviously it's about the point, however fostering that theme so your paper is convincing http://learninghappenshere.com/. Plunking down and dealing with the different parts of your subject ought to be all around as compensating as the actual research, so we should examine how this should be possible.
