For a detailed dis- cussion, including examples and usage recommendations, refer to the GNU Dico Manual available in texinfo format. If the info reader and GNU Dico documentation are properly installed on your system, the command info dico should give you access to the complete manual. You can also view the manual using the info mode in emacs(1), or find it in various formats online at http://www.gnu.org.ua/software/dico/manual If any discrepancies occur between this manpage and the GNU Dico Manu- al, the later shall be considered the authoritative source. DESCRIPTION Console-based utility for querying dictionary servers. It has two op- eration modes. In single query mode, dico performs a query, displays its result and exits immediately. This mode is enabled if a word or a URL was given in the command line. In interactive mode, dico enters a read-and-eval loop, in which it reads requests from the keyboard, performs the necessary searches, and displays obtained results on the screen. Upon startup, dico looks for initialization files named .dico in the current user's home directory, and the current working directory. If found, these files are read in order, and their contents is treated as a sequence of commands, which are executed. See the section COMMANDS, for a discussion of available commands. OPTIONS Server Selection -d, --database=NAME]fR Select database to search. --host=SERVER Connect to this server. -p, --port=SERVICE Specify port to connect to. --source=ADDR Set source address for TCP connections. Operation Modes -D, --dbs Show available databases. -H, --serverhelp Show server help. -I, --serverinfo Show information about the server. -S, --strategies Show available search strategies. -i, --info=DBNAME Show information about database DBNAME. --levdist, --levenshtein-distance=N Set maximum Levenshtein distance to N. -m, --match Match instead of define. -q, --quiet Do not print the normal dico welcome banner. -s, --strategy=NAME Select a strategy for matching. Implies --match. Authentication -a, --noauth Disable authentication. --autologin=NAME Set the name of autologin file to use. -c, --client=STRING Additional text for client command. -k, --key, --password=STRING Set shared secret for authentication. --nosasl Disable SASL authentication. --sasl Enable SASL authentication (default). -u, --user=NAME Set user name for authentication. Debugging --source-info Include source line information in the debugging output. -t, --transcript Enable session transcript. --time-stamp Include time stamp in the debugging output. -v, --verbose Increase debugging verbosity level. Other Options -V, --version Print program version. -h, --help Print a short summary of command line options. --usage Display a short usage message. COMMANDS In interactive mode dico reads commands from the standard input, exe- cutes them and displays results on the standard output. If the stan- dard input is connected to a terminal, the readline and history facili- ties are enabled. The input syntax is designed so as to save you the maximum amount of typing. A line beginning with a # sign introduces a comment and is ignored. Typing quiestion mark alone shows a short usage summary. All commands begin with a command prefix, a single punctuation charac- ter used to tell a command from a define or match request. The default command prefix is a dot. Any input starting with a slash is a match request. For example, /sail will display all headwords matching the word sail in the currently se- lected database. Any input not starting with / or command prefix is a definition re- quest. It is looked up using the defaault server and database set- tings, and the result is displayed on the screen. Dico initialization files have the same syntax, excepting that no com- mand prefix is used by default. Available commands (without prefix) are summarized in the table below: autologin FILE Use FILE for authentication. If FILE begins with ~/, this pre- fix is replaced with the name of the current user home directo- ry, followed by /. The prefix ~USER/ is replaced with the home directory of USER. This command is mostly useful in the ini- tialization file. See the section AUTOLOGIN FILE, for a discussion of this fea- ture. close Close the existing connection. database [NAME] Without argument, display the currently selected database. With argument, select the database NAME. distance [N] If the remote server supports xlev experimental capability, this command shows the maximum Levenshtein distance. With argument, it sets the distance. help Displays short command usage summary. For convenience, a single question mark can be used instead of this command. history Show command history. info [NAME] Display information about the database NAME, or the currently selected database, if used without arguments. ld List databases. ls List strategies. open HOST [PORT] Establish connection with remote server HOST. If given, use PORT instead of the default 2628. pager [COMMAND] Sets or displays external command used for paging output. prefix [CHAR] Without argument, shows the currently selected command prefix. With argument, sets command prefix to the given value. prompt STRING Sets dico command line prompt. quiet yes|no Toggle the startup banner. Useful in the initialization file. quit Quit the dico shell. sasl [yes|no] Without argument, show whether the SASL authentication is en- abled. With argument, enable or disable it. strategy [NAME] Without argument, display the currently selected matching strateguy. With argument, select the strategy NAME. transcript [yes|no] Enable or disable session transcript. When the transcript is on, dico displays raw DICT commands and answers as they are exe- cuted. It is useful for debugging purposes. Used without arguments, this command shows current state of the transcript. version Print program version. warranty Print the copyright statement. AUTOLOGIN FILE After connecting to a remote server, dico checks if the server supports authentication and attempts to authenticate itself if so. The authen- tication credentials are taken from the following sources: 1. Command line options --user and --password. 2. URL given as a command line argument. 3. Autologin files. These three sources are consulted in that order, i.e., a user name sup- plied with the --user command line option takes precedence over the one found in an URL and over any names supplied by autologin files. If, after consulting all these sources, the user name is established, while the password is not, the resulting action depends on whether the standard input is connected to a terminal. If it is, dico will ask the user to supply a password. If it is not, authentication is aborted and connection to the server is closed. Some authentication mechanisms require additional credentials. For ex- ample, GSSAPI authentication requires a service name. These creden- tials can be supplied only in autologin file. Autologin file is a plaintext file that contains authentication infor- mation for various DICT servers. At most two autologin files are con- sulted: first the session-specific file, if it is supplied by autologin command or by the --autologin command line option, next the default file .dicologin in the user's home directory. The default autologin file is examined only if no matching record was found in the session- specific one. The file format is similar to that of .netrc. Empty lines and comments are ignored. Comments are introduced by a pound sign. Non-empty lines constitute statements. Tokens in a state- ment are separated with spaces, tabs, or newlines. A valid statement must begin with one of the following: machine NAME This statement contains parameters for authenticating on server NAME. default This statement contains parameters for authenticating on any server, not explicitly listed in one of the machine statements. There can be at most one default statement in autologin file. Its exact location does not matter, it will always be matched after all explicit machine statements. The following clauses can follow: login NAME Supplies the user name for this server. password STRING Supplies the password for this server. noauth Do not perform authentication on this server. sasl Enable SASL authentication. nosasl Disable SASL authentication. mechanisms LIST Declare acceptable SASL mechanisms. The LIST argument is a com- ma-separated list of mechanism names, without intervening white- space. Multiple mechanisms clauses may be present, in which case the corresponding lists are concatenated. service NAME Declare service name, for authentication methods that need it. If this token is omitted, the default service name dico is used. realm NAME Declare realm for authentication. host NAME Set host name for this server. By default, it is determined au- tomatically.
