BIBLE(1)		     General Commands Manual			BIBLE(1)

NAME
     bible - Lookup words and verses in the Bible (King James version)

SYNOPSIS
     bible  [-f]  [-l  columns]  [-m memlimit] [-p path-list] [-d datafile-name]
     [verse-reference(s)]

DESCRIPTION
     Bible writes the text of specified Bible verses to stdout.  The  text  used
     is  the  Authorized  (King James) version.  Commands may be given either on
     the command line, or interactively.  Bible also supports  instant	searches
     for verses containing a particular word, or combination of words.	The pro-
     gram  uses  a  specially-compressed  form of the text that allows for rapid
     random access, while still compressing the original  4.4  Mbyte  text  into
     less  than  1.8  Mbytes  (plus  the "concordance" data file, which requires
     nearly 900 Kbytes).

   Options
     The options to bible are:

     -f 	    Toggles special output formatting (pretty-printing).  By de-
		    fault, pretty-printing is on (a  change  from  earlier  ver-
		    sions).   When  pretty-printing  is off, bible precedes each
		    verse with its book/chapter/verse reference.   When  pretty-
		    printing  is  on, the book name and chapter are printed on a
		    line by themselves,  and  only  when  the  chapter	or  book
		    changes.   The  start of each verse is indented and preceded
		    by the verse number.  The book and chapter names  are  sepa-
		    rated  from  the text by blank lines to facilitate post-pro-
		    cessing by other tools such as adjust.  Pretty-printing  ac-
		    tivates automatic line breaks ( -l)

     -l columns     When  pretty-printing  is  off,  bible  prints one verse per
		    line, even though the text may be much longer than will  fit
		    on	a single line of a display.  This is very handy when the
		    output will be processed by other programs, but  it  doesn't
		    look very nice.  The -l option sets a limit on the length of
		    an	output	line, causing bible to break lines (only between
		    words) to fit.  The columns argument is optional; if  it  is
		    not specified, bible will use the value of the COLUMNS envi-
		    ronment variable minus one.  If COLUMNS is not set a default
		    value of 79 is used.

     -m memlimit    Bible  normally  allocates	up  to 1 megabyte for buffers to
		    store uncompressed text.  If the -m option is present, bible
		    will set the limit to memlimit kilobytes.

     -p path-list   Bible normally searches for the text data file first in  the
		    current  directory,  and then in /usr/local/lib.  The -p op-
		    tion may be used  to  change  the  search  path.   Path-list
		    should  be	a list of directories, each separated by a space
		    (be sure to escape them from the shell).

     -d filename    Bible normally expects to find the text data in a file named
		    bible.data, and the concordance data in bible.data.conc.  If
		    the -d option is present, bible will look for  a  text  data
		    file named filename, and a concordance data file named file-
		    name.conc instead.

   Verse References
     Bible  accepts  verse  references	in  a variety of forms, including single
     verses and verse ranges.  For example:

	 Jn3:16, john3:16,17 ps1:1-6

     Most recognizable abbreviations are allowed, and spelling	errors	are  ig-
     nored if the book can be made out in the first few characters.  No distinc-
     tion is made between upper and lower case.  Multiple references may be pro-
     vided on an input line, delimited by spaces or commas.

     Verse  and  chapter  will	be silently coerced into a realistic range, e.g.
     "Ps1:87" will be treated as Psalm 1:6 since there are only  six  verses  in
     Psalm 1, and "Rev99:99" will be treated as Revelation 22:21 (the last verse
     in the Bible).  A book name by itself is assumed to be a reference to chap-
     ter  1,  verse 1 of that book, i.e. "Acts" is the same as "Acts1:1".  Simi-
     larly, a book and chapter without a verse is assumed to refer to verse  one
     of that chapter.

     A range of verses may be printed by giving a starting and ending reference,
     separated	by a hyphen ("-").  For example, "Gen1:1-Rev22:21" will dump the
     entire text (about 4.4 MB).

     Bible keeps track of your current context and  will  attempt  to  interpret
     references in that context.  For example if you request "John1:1", followed
     by  "3:16", and then "17", the second reference is assumed to be within the
     book of John, and the third is assumed to be within chapter 3 of that book.
     An empty reference, e.g. a blank line on the  input,  will  show  the  next
     verse following the last one displayed.

     More examples of legal verse references:

	 psalms1

	 Psalms

	 Romans3:23 5:8 6:23

	 1

	 5:1

	 1-22

   Concordance (Word Searches)
     Bible  includes  a concordance, with which you can immediately find all the
     verses in which a word appears.  The ??word command  will	select	all  the
     references  that  include	word.  Bible will display the number of matching
     references, if any, but since the number could be quite large, it won't ac-
     tually list the references until you ask.

     In order to list the references from a word search, the ?list (or ?l)  com-
     mand is used.  Likewise, to print the full text of the verses selected by a
     word search, use the ?view (or ?v) command.

     The  lists  for  multiple words may be combined using the ?and word and ?or
     word commands.  First create a reference list using the ??   command.   For
     example,

	 ??faith

     will  find 231 references to the word "faith".  To narrow the list further,
     the command

	 ?and love

     will inform you that, while there were 281 references to "love", only 16 of
     them were also in the previous reference list (i.e. contained both  words).
     The  "combined  list" of 16 references produced by the ?and word command is
     the intersection of the two lists,  and  replaces	the  original  reference
     list.

     The  ?list and ?view commands will now apply to the combined list.  You can
     continue to apply the ?and command to the combined list.  For example,

	 ?and hope

     will further narrow the combined list to only two references.  Typing ?view
     then displays the full text:

	 1 Thessalonians 1

	   3 Remembering without ceasing your work of faith, and labour of
	 love, and patience of hope in our Lord Jesus Christ, in the
	 sight of God and our Father;

	 1 Thessalonians 5

	   8 But let us, who are of the day, be sober, putting on the
	 breastplate of faith and love; and for an helmet, the	hope  of  salva-
     tion.

     The  ?or word command is similar to ?and, but it produces a combined refer-
     ence list that is the union of the two lists.  In other words, the list in-
     cludes those verses in which either of the words appears.	For example

	 ??angels
	 ?or angel

     will find all 283 verses in wich either word is used.

     By default, reference lists cover the entire Bible.  But  for  those  times
     when  it is useful to limit them to a particular section of the text, bible
     provides the ?in verse range command.  For example

	 ?in mt1:1-rev22:21

     will limit future reference lists to the New Testament.  If you have a cur-
     rent reference list, references  that  fall  outside  the	limits	will  be
     dropped.	Note that only a contiguous range of verses may be used.  To re-
     set the limits so that the whole text is searched, the command is ?in all.

   Interactive Use
     For interactive use, invoke bible without any verse references on the  com-
     mand line.  You should see a prompt displayed:

	 Bible(KJV) [Gen1:1]>

     Typing ?  will print a command summary.

     The program accepts three types of interactive command input:

	    *  Bible verse references, as described above.
	    *  Concordance  (word search) commands, also described above.  These
	       commands are: ??, ?list, ?view, ?and, ?or, and ?in.
	    *  Miscellaneous program control commands:

	    ?, ?h, ?help   Prints help text.
	    ?f		   Toggles output formatting modes.
	    ?wfile	   Begin writing program output to a file.  If file  ex-
			   ists, output is appended to what's there already.
	    ?w		   Stop writing to a file.
	    >, <	   Toggle  the	direction (forward or backward) in which
			   bible will move through the text when a blank line is
			   entered.
	    q, ?bye, ?exit, ?quit, ?q
			   End the program.

BUGS
     References to the one-chapter books of Philemon and 3 John are non-standard
     in that they require a dummy chapter number.  For example, use  Phm1:5  in-
     stead of Phm5 to get verse 5.

     The  possessive form 's is handled strangely by the Concordance.  The apos-
     trophe has been removed and the s has been treated as if it were a separate
     word.  So, for example, if you wanted to find all references to "refiner's"
     you would have to first search for "refiner" (using the command  ??refiner)
     and then combine it with a search for "s" (?and s).

     The  convention for handling partial verse specifications can be clumsy.  A
     book name by itself, e.g. "Matthew" is taken as a reference to verse 1:1 of
     that book.  So ?in matt results in a range limit of a single verse  (Mt1:1)
     instead of the whole book as one might hope.  Similarly, ?in mt-rev results
     in  a  range of Matthew 1:1 to Revelation 1:1, instead of extending all the
     way to Revelation 22:21.

AUTHOR
     Chip Chapin, Hewlett Packard Company (chip@cup.hp.com).

     The current version uses Lempel-Ziv-Welch compression  on	the  data  file,
     though  I	modified the "compress" program to emit checkpoints at known in-
     tervals to facilitate random access to the data.  I call this simple  tech-
     nique "windowed compression", and it could be used for any similar applica-
     tion.   The  data	file  can still be uncompressed using the standard "com-
     press" utility if my file header is removed.

     I would like to gratefully acknowledge the contribution of the  authors  of
     the  compress  program, which I modified for use in the text storage compo-
     nent of bible.  As listed in the compress	sources  they  are:  Spencer  W.
     Thomas, Jim McKie, Steve Davies, Ken Turkowski, James A. Woods, Joe Orost.

     Matthew Vernon <matthew@debian.org> has substantially updated a the code of
     this package. His alterations are made available under the terms of the GNU
     General  Public Licence, version 2 or later, as published by the Free Soft-
     ware Foundation.
