ptx

ptx [OPTION]... [INPUT]...
ptx -G [OPTION]... [INPUT [OUTPUT]]

Produce a permuted index of file contents Output a permuted index, including context, of the words in the input files. Mandatory arguments to long options are mandatory for short options too. With no FILE, or when FILE is -, read standard input. Default is '-F /'.

Options

--auto-reference, -A

output automatically generated references

--traditional, -G

behave more like System V 'ptx'

--flag-truncation=<STRING>, -F <STRING>

use STRING for flagging line truncations

--macro-name=<STRING>, -M <STRING>

macro name to use instead of 'xx'

--format=roff, -O

generate output as roff directives

--right-side-refs, -R

put references at right, not counted in -w

--sentence-regexp=<REGEXP>, -S <REGEXP>

for end of lines or end of sentences

--format=tex, -T

generate output as TeX directives

--word-regexp=<REGEXP>, -W <REGEXP>

use REGEXP to match each keyword

--break-file=<FILE>, -b <FILE>

word break characters in this FILE

--ignore-case, -f

fold lower case to upper case for sorting

--gap-size=<NUMBER>, -g <NUMBER>

gap size in columns between output fields

--ignore-file=<FILE>, -i <FILE>

read ignore word list from FILE

--only-file=<FILE>, -o <FILE>

read only word list from this FILE

--references=<FILE>, -r <FILE>

first field of each line is a reference

--width=<NUMBER>, -w <NUMBER>

output width in columns, reference excluded

Examples

Generate a permuted index where the first field of each line is an index reference:

ptx --references {{path/to/file}}

Generate a permuted index with automatically generated index references:

ptx --auto-reference {{path/to/file}}

Generate a permuted index with a fixed width:

ptx --width={{width_in_columns}} {{path/to/file}}

Generate a permuted index with a list of filtered words:

ptx --only-file={{path/to/filter}} {{path/to/file}}

Generate a permuted index with SYSV-style behaviors:

ptx --traditional {{path/to/file}}
