Name
       ptx - create permuted index

Syntax
       ptx [option...] [input[output]]

Description
       The  command  generates	a permuted index to file input on file output (standard input and output default).  It has three phases: the first
       does the permutation, generating one line for each keyword in an input line.  The keyword is rotated to the front.  The	permuted  file	is
       then  sorted.   Finally,  the  sorted lines are rotated so the keyword comes at the middle of the page.	The command produces output in the
       form:

	      .xx "tail" "before keyword" "keyword and after" "head"

       where .xx may be an or macro for user-defined formatting.  The before keyword and keyword and after fields incorporate as much of the  line
       as  fits  around  the keyword when it is printed at the middle of the page.  The and commands, at least one of which is an empty string "",
       are wrapped-around pieces small enough to fit in the unused space at the opposite end of the line.  When original text must  be	discarded,
       `/' marks the spot.

Options
       The following options can be applied:

       -b break 	   Use	the  characters in the break file as separators.  In any case, tab, new line, and space characters are always used
			   as break characters.

       -f		   Folds upper and lower case letters for sorting.

       -g n		   Uses specified number as interfield gap.  The default gap is 3 characters.

       -i ignore	   Do not use as keywords any words given in the ignore file.  If the -i and -o options are missing, use /usr/lib/eign	as
			   the ignore file.

       -o only		   Use words listed only in the only file.

       -r		   Uses leading nonblanks as reference identifiers.  Attach that identifier as a 5th field on each output line.

       -t		   Prepares the output for the phototypesetter.  The default line length is 100 characters.

       -w n		   Use the next argument, n, as the width of the output line.  The default line length is 72 characters.

Restrictions
       Line length counts do not account for overstriking or proportional spacing.

NAME

       ptx - permuted index

SYNOPSIS

       ptx [ option ] ...  [ input [ output ] ]

DESCRIPTION

       Ptx  generates  a permuted index to file input on file output (standard input and output default).  It has three phases: the first does the
       permutation, generating one line for each keyword in an input line.  The keyword is rotated to  the  front.   The  permuted  file  is  then
       sorted.	Finally, the sorted lines are rotated so the keyword comes at the middle of the page.  Ptx produces output in the form:

	      .xx "tail" "before keyword" "keyword and after" "head"

       where  .xx  may	be an nroff or troff(1) macro for user-defined formatting.  The before keyword and keyword and after fields incorporate as
       much of the line as will fit around the keyword when it is printed at the middle of the page.  Tail and head, at least one of which  is	an
       empty  string  "",  are	wrapped-around pieces small enough to fit in the unused space at the opposite end of the line.	When original text
       must be discarded, `/' marks the spot.

       The following options can be applied:

       -f     Fold upper and lower case letters for sorting.

       -t     Prepare the output for the phototypesetter; the default line length is 100 characters.

       -w n   Use the next argument, n, as the width of the output line.  The default line length is 72 characters.

       -g n   Use the next argument, n, as the number of characters to allow for each gap among the four parts of the  line  as  finally  printed.
	      The default gap is 3 characters.

       -o only
	      Use as keywords only the words given in the only file.

       -i ignore
	      Do  not  use  as keywords any words given in the ignore file.  If the -i and -o options are missing, use /usr/share/misc/eign as the
	      ignore file.

       -b break
	      Use the characters in the break file to separate words.  In any case, tab, newline, and space characters are always  used  as  break
	      characters.

       -r     Take  any  leading  nonblank  characters of each input line to be a reference identifier (as to a page or chapter) separate from the
	      text of the line.  Attach that identifier as a 5th field on each output line.

       The index for this manual was generated using ptx.
