mkdic

MKDIC(1)						      General Commands Manual							  MKDIC(1)

NAME

       mkdic - Tool for creating a user dictionary

SYNOPSIS

       mkdic [{-cs|-cannaserver} canna-server] [-s] [- | -l local-file] remote-dic

DESCRIPTION

       mkdic  creates  user dictionary named remote-dic in the user dictionary directory of the remote host, on which cannaserver(1M) is in opera-
       tion.  Dictionary file name remote-dic is assigned to this file at this time.

       If the - and -l option isn't specified, mkdic creates an empty dictionary.

       If the - option is specified, the standard input will be used as the dictionary file. If the -l option is  specified,  local-file  will	be
       used as the dictionary file.

       If the user dictionary directory does not exist, it will be created.

       Dictionary  directory  file  -- dics.dir -- is rewritten automatically after the registering. The registered dictionary can thus be used by
       writing the dictionary name into the customize file.

OPTIONS

       -cs canna-server (or -cannaserver canna-server)
		   Specifies the server machine that contains the dictionary to be created.

       -s	   Indicates that the dictionary to be created is an adjunct dictionary.  If this option is omitted, the dictionary will  be  cre-
		   ated as an independent-word one.

       -l local-file
		   Registers the input data from local-file.

       -	   The standard input will be used as the dictionary file.

EXAMPLES(1) If you want to creat an empty dictionary file:

	     % mkdic test(2) If you want to register the input data from the standard input:

	     % mkdic test -

       Registers  the  input data from the standard input, in the user dictionary directory under dictionary name ``test''.  The following line is
       then added to dictionary directory file -- dics.dir -- :

		 user1.t(.mwd) -test-(3) If the dictionary file is specified:

	     % mkdic test -l test1.t

       Registers independent-word dictionary file ``test1.t'' in the remote host's user dictionary directory under dictionary name ``test''.   The
       following line is then added to dics.dir:

		user1.t(.mvd) -test-

       user1.t is a dictionary file name generated automatically by the system.
