# DICT dictionary server protocol

I have often found myself browsing the web just to look up some word
definition. This seems a terrible waste of resources just to find out
the meaning of a word, and then I remembered there is a protocol that
provides this. That protocol is DICT[1].

As with many protocols from the golden era of computing, it can be
utilized without a specialized client.


## Some examples

> $telnet dict.org 2628
> Trying 199.48.130.6...
> Connected to dict.org.
> Escape character is '^]'.

Type 'help'.

> help
> 113 help text follows
> DEFINE database word         -- look up word in database
> MATCH database strategy word -- match word in database using str..
> SHOW DB                      -- list all accessible databases
> SHOW DATABASES               -- list all accessible databases
> SHOW STRAT                   -- list available matching strategies
> SHOW STRATEGIES              -- list available matching strategies
> SHOW INFO database           -- provide information about the da..
> SHOW SERVER                  -- provide site-specific information
> OPTION MIME                  -- use MIME headers
> CLIENT info                  -- identify client to server
> AUTH user string             -- provide authentication information
> STATUS                       -- display timing information
> HELP                         -- display this help information
> QUIT                         -- terminate connection

To do a basic word search of all databases.

> d gopher

To do a word search of a specific database.

> d foldoc gopher
> 150 1 definitions retrieved
> 151 "gopher" foldoc "The Free On-line Dictionary of Computing (3..
> gopher

If you want to script something or just use it from the command line
then you can do something like the following:

> $echo "d foldoc gopher" | nc -N dict.org 2628 | less
 

## Conclusion

There are many dictionaries available so this is a very useful
resource.

I thought about writing a gopher interface to DICT, but maybe it's
worth learning a bit about the protocol[2]. I may come back to it if
there is any interest...
