I need to look in /usr/share/dict/words for a 5-letter word that starts with d or D, followed by a lowercase vowel, and ends with s. I have tried everything but to no avail.

grep '^[dD][aeiou]..s$' /usr/share/dict/words
  • ^[dD] - match d or D at the beginning of the line
  • [aeiou] - match a, e, i, o or u
  • .. - match any two characters
  • s$ - match s, followed by the end of the line
  • Note that in my (British) /usr/share/dict/words, there are a lot more vowels than the aeiou characters (even if you don't want to consider y as a vowel). Also note that . matches any character, not only letters (it will typically match the apostrophe in the words file). – Stéphane Chazelas May 8 '13 at 15:38
