So far I am using grep -E '[aeiou]{2}' /usr/share/dict/american-english
. This is giving me two vowels, but I want them to be only vowels in a row, like "tooth", "beer", etc.
So I want to use grep to get a word with a vowel, but only if that vowel is followed by the same vowel. Like, I want to find tooth, I want to see if I can write a command that will look for the first o
and see the next character is a o
. Is that more clear?
What am I missing?
