NAME
dict - DICT Protocol Client
SYNOPSIS
dict word
dict [options] [word]
dict [options] dict://host:port/d:word:database
dict [options] dict://host:port/m:word:database:strategy
DESCRIPTION
dict is a client for the Dictionary Server Protocol (DICT), a TCP
transaction based query/response protocol that provides access to dic-
tionary definitions from a set of natural language dictionary data-
bases. Exit status is 0 if operation succeeded, or non-zero otherwise.
See EXIT STATUS section.
OPTIONS
-h server or --host server
Specifies the hostname for the DICT server. Server/port combi-
nations can be specified in the configuration file. If no
servers are specified in the configuration file or on the com-
mand line, dict will fail. If IP lookup for a server expands to
a list of IP addresses (as dict.org does currently), then each
IP will be tried in the order listed.
-p service or --port service
Specifies the port (e.g., 2628) or service (e.g., dict) for con-
nections. The default is 2628, as specified in the DICT Proto-
col RFC. Server/port combinations can be specified in the con-
figuration file.
-d dbname or --database dbname
Specifies a specific database to search. The default is to
search all databases (a "*" from the DICT protocol). Note that
a "!" in the DICT protocol means to search all of the databases
until a match is found, and then stop searching.
-m or --match
Instead of printing a definition, perform a match using the
specified strategy.
-s strategy or --strategy strategy
Specify a matching strategy. By default, the server default
match strategy is used. This is usually "exact" for defini-
tions, and some form of spelling-correction strategy for matches
("." from the DICT protocol). The available strategies are de-
pendent on the server implementation. For a list of available
strategies, see the -S or --strats option.
-C or --nocorrect
Usually, if a definition is requested and the word cannot be
found, spelling correction is requested from the server, and a
list of possible words are provided. This option disables the
generation of this list.
-c file or --config file
Specify the configuration file. The default is to try ~/.dictrc
and /etc/dictd/dict.conf, using the first file that exists. If
a specific configuration file is specified, then the defaults
will not be tried.
-D or --dbs
Query the server and display a list of available databases.
-S or --strats
Query the server and display a list of available search strate-
gies.
-H or --serverhelp
Query the server and display the help information that it pro-
vides.
-i dbname or --info dbname
Request information on the specified database (usually the
server will provide origination, descriptive, or other informa-
tion about the database or its contents).
-I or --serverinfo
Query the server and display information about the server.
-M or --mime
Send OPTION MIME command to the server.
NOTE: Server's capabilities are not checked.
-f or --formatted
Enables formatted output, i.e. output convenient for postpro-
cessing by standard UNIX utilities. No, it is not XML ;-) Also
error and warning messages like
" No matches...", " Invalid strategy..." etc. are sent to
stderr, not to stdout.
Format:
-I, -i, -H and similar:
host<TAB>port
<SPC><SPC>line1
<SPC><SPC>line2
...
-S:
host<TAB>port<TAB>strategy1<TAB>short description1
host<TAB>port<TAB>strategy2<TAB>short description2
...
-D:
host<TAB>port<TAB>database1<TAB>database description1
host<TAB>port<TAB>database2<TAB>database description2
...
-m:
host<TAB>port<TAB>database1<TAB>match1
host<TAB>port<TAB>database2<TAB>match2
...
-a or --noauth
Disable authentication (i.e., don't send an AUTH command).
-u user or --user user
Specifies the username for authentication.
-k key or --key key
Specifies the shared secret for authentication.
-V or --version
Display version information.
-L or --license
Display copyright and license information.
-4 Forces dict to use IPv4 addresses only.
-6 Forces dict to use IPv6 addresses only.
--help Display help information.
-v or --verbose
Be verbose.
-r or --raw
Be very verbose: show the raw client/server interaction.
--pipesize
Specify the buffer size for pipelineing commands. The default
is 256, which should be sufficient for general tasks and be be-
low the MTU for most transport media. Larger values may provide
faster or slower throughput, depending on MTU. If the buffer is
too small, requests will be serialized. Values less than 0 and
greater than one million are silently changed to something more
reasonable.
--client text
Specifies additional text to be sent using the CLIENT command.
--debug flag
Set a debugging flag. Valid flags are:
verbose
The same as -v or --verbose.
raw The same as -r or --raw.
scan Debug the scanner for the configuration file.
parse Debug the parser for the configuration file.
pipe Debug TCP pipelining support (see the DICT RFC and
RFC1854).
serial Disable pipelining support.
time Perform transaction timing.
CONFIGURATION
The configuration file currently has a very simple format. Lines are
used to specify servers, for example:
server dict.org
or, with options:
server dict.org { port 8080 }
server dict.org { user username secret }
server dict.org { port dict user username secret }
the port and user options may be specified in any order. The port op-
tion is used to specify an optional port (e.g., 2628) or service (e.g.,
dict) for the TCP/IP connection. The user option is used to specify a
username and shared secret to be used for authentication to this par-
ticular server.
Servers are tried in the order listed until a connection is made.

BUGS
If a dict: URL is given on the command line, only the first one is
used. The rest are ignored.
If a dict: URL contains a specifier for the nth definition or match of
a word, it will be ignored and all the definitions or matches will be
provided. This violates the RFC, and will be corrected in a future re-
lease.
If a dict: URL contains a shared secret, it will not be parsed cor-
rectly.
When OPTION MIME command is sent to the server (-M option) , server's
capabilities are not checked.
