Top Forums UNIX for Dummies Questions & Answers Comparing lines within a word list Post 302954641 by dtalvacchio on Wednesday 9th of September 2015 02:37:06 PM

Hello, thank you all for your replies, and apologies for the delay in responding in kind. Let me try to address all of your questions/comments. First, Don, hopefully the attached screenshot answers the bit about the OS and shell.

Now if I can clarify the problem I'm trying to solve. For the sake of simplicity let's say we're only dealing with a long list of three-letter words. What I am looking for are sets of words that share exactly (as opposed to at least) two letters in the same position. So if we roughly imagine a list of all three-letter words that are in some reliable English-language dictionary, one such set that would result from the search would be:

ACE
ADE
AGE
ALE
APE
ARE
ATE
AVE
AWE
AXE
AYE

And what I want is all such sets, for every permutation of the two fixed letters. Does that clarify the problem?

Thanks very much-- Dominick

manx

WORDS(5)						     Linux Programmers Manual							  WORDS(5)

NAME

       manx - a list of Manx Gaelic words

DESCRIPTION

       /usr/share/dict/manx is an ASCII file which contains an alphabetic list of words, one per line.

FILES

       /etc/dictionaries-common/words  is  a  symbolic	link  to  a  /usr/share/dict/<language> file.  /usr/share/dict/words is a symbolic link to
       /etc/dictionaries-common/words, and is the name by which other software	should	refer  to  the	system	word  list.   See  select-default-
       wordlist(8) for more information.

       The directory /usr/share/dict can contain word lists for many languages, with name of the language in English, e.g., /usr/share/dict/french
       and /usr/share/dict/danish contain respectively lists of French and Danish words if they exist.	Such lists should be coded using  the  ISO
       8859-1 character set encoding.

SEE ALSO

       ispell(1), select-default-wordlist(8), and the Filesystem Hierarchy Standard.

HISTORY

       The words lists are not specific, and may be generated from any number of sources.

       The  system word list used to be /usr/dict/words.  For compatibility, software should check that location if /usr/share/dict/words does not
       exist.

AUTHOR

       Word lists are collected and maintained by various authors.
