UNIX for Dummies Questions & Answers

hi

i have created a pipe which outputs a list of words such as:

Code:

hello
yay
foo
yah
good
goof

and from this i want to find words which only differ by their last letters ie yay/yah and good/goof.

i would only need to print out the first instance of the word.
these words are not always adjacent as even after sorting, there may be other words which come in between these.

any ideas anyone?

good/goof and yah/yay will be adjacent after a sort. The only words that could separate them would be stuff like gooe and yap, thus giving you a triple instead of a double match.
