I don't like using multiple commands.

    mawk 'BEGIN{b = "[abcdefois]"; l = "[a-z]"; W = "^" b l l l l l "$"}; $0 ~ W {print "#" toupper($0);}' /usr/share/dict/words

I came up with:

  gawk 'BEGIN {IGNORECASE=1} ((length($1) == 6) && /^[a-fois]+$/) {gsub(/o/,0);gsub(/i/,1);gsub(/s/,5); print toupper("#"$1)}' /usr/share/dict/words

(caveat: it does not filter out duplicates)

You can also do it entirely in sed:

    sed -E -e '/^[a-fio]{6}$/!d; y/abcdefioIO/ABCDEF1010/; s/^/#/' /usr/share/dict/words

This produces 35 items. The grep version gives 93

Yeah, I failed to make the pattern case insensitive.

Here's a fixed version that also handles S/5:

    sed -E -e '/^[A-FIOSa-fios]{6}$/!d; y/abcdefiosIOS/ABCDEF105105/; s/^/#/' /usr/share/dict/words

you also aren't going to get valid color codes
