Is it "grep'

[william crosby]

Hello,

I hope someone can help me. A friend of mine told me there are three words
in the english language that end in the letters 'gry'. I immediately came
up with angry and hungry. I've seen on the net where people use a command
and a wild card to find out different groups of words. I tried using grep 
but I don't understand how to do it. It would be greatly appreciated if
someone could tell me exactly how to do it.

Thanks, Bill
