ptx
PTX(1) General Commands Manual PTX(1)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/lib/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.

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