=head1 NAME
|
|
|
|
dict - a perl client for accessing network dictionary servers
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<dict> [OPTIONS] I<word>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<dict> is a client for the Dictionary server protocol (DICT),
|
|
which is used to query natural language dictionaries hosted on
|
|
a remote machine. When used in the most simple way,
|
|
|
|
% dict word
|
|
|
|
B<dict> will look for definitions of I<word> in the dictionaries
|
|
hosted at B<dict.org>. If no definitions are found, then dict
|
|
will look for words which are similar, and list them:
|
|
|
|
% dict bonana
|
|
no definition for "bonana" - perhaps you meant:
|
|
banana, bonanza, Banana, Bonanza, Bonasa
|
|
|
|
This feature is only available if the remote DICT server supports
|
|
the I<soundex> or I<Levenshtein> matching strategies.
|
|
You can use the B<-stats> switch to find out for yourself.
|
|
|
|
You can specify the hostname of the DICT server using the B<-h> option:
|
|
|
|
% dict -h dict.org dictionary
|
|
|
|
A DICT server can support a number of databases;
|
|
you can use the B<-d> option to specify a particular database.
|
|
For example, you can look up computer-related terms
|
|
in the Free On-line Dictionary Of Computing (FOLDOC) using:
|
|
|
|
% dict -h dict.org -d foldoc byte
|
|
|
|
To find out what databases (dictionaries) are available on
|
|
a server, use the B<-dbs> option:
|
|
|
|
% dict -dbs
|
|
|
|
There are many dictionaries hosted on other servers around the net;
|
|
a list of some of them can be found at
|
|
|
|
http://www.dict.org/links.html
|
|
|
|
=head2 MATCHING
|
|
|
|
Instead of requesting word definitions, you can use dict
|
|
to request a list of words which match a pattern.
|
|
For example, to look for four-letter words starting in 'b'
|
|
and ending in 'p', you would use:
|
|
|
|
% dict -match -strategy re '^b..p$'
|
|
|
|
The B<-match> option says you want a list of matching words rather
|
|
than a definition.
|
|
The B<-strategy re> says to use POSIX regular expressions
|
|
when matching the pattern B<^b..p$>.
|
|
|
|
Most DICT servers support a number of matching strategies;
|
|
you can get a list of the strategies provided by a server
|
|
using the B<-strats> switch:
|
|
|
|
% dict -h dict.org -strats
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-h> I<server> or B<-host> I<server>
|
|
|
|
The hostname for the DICT server. If one isn't specified
|
|
then defaults to B<dict.org>.
|
|
|
|
=item B<-p> I<port> or B<-port> I<port>
|
|
|
|
Specify the port for connections (default is 2628, from RFC 2229).
|
|
|
|
=item B<-d> I<dbname> or B<-database> I<dbname>
|
|
|
|
The name of a specific database (dictionary) to query.
|
|
|
|
=item B<-m> or B<-match>
|
|
|
|
Look for words which match the pattern (using the specified strategy).
|
|
|
|
=item B<-i> I<dbname> or B<-info> I<dbname>
|
|
|
|
Request information on the specified database.
|
|
Typically results in a couple of pages of text.
|
|
|
|
=item B<-c> I<string> or B<-client> I<string>
|
|
|
|
Specify the CLIENT identification string sent to the DICT server.
|
|
|
|
=item B<-D> or B<-dbs>
|
|
|
|
List the available databases (dictionaries) on the DICT server.
|
|
|
|
=item B<-s> I<strategy> or B<-strategy> I<strategy>
|
|
|
|
Specify a matching strategy. Used in combination with B<-match>.
|
|
|
|
=item B<-S> or B<-strats>
|
|
|
|
List the matching strategies (used in -strategy) supported
|
|
by the DICT server.
|
|
|
|
=item B<-I> or B<-serverinfo>
|
|
|
|
Request information on the selected DICT server.
|
|
|
|
=item B<-help>
|
|
|
|
Display a short help message including command-line options.
|
|
|
|
=item B<-doc>
|
|
|
|
Display the full documentation for B<dict>.
|
|
|
|
=item B<-version>
|
|
|
|
Display the version of B<dict>
|
|
|
|
=item B<-verbose>
|
|
|
|
Display verbose information as B<dict> runs.
|
|
|
|
=item B<-debug>
|
|
|
|
Display debugging information as B<dict> runs.
|
|
Useful mainly for developers.
