NAME
deroff − Deletes neqn, nroff, and tbl constructs
SYNOPSIS
deroff [-i | -l] [-kpuw] [-ma | -me | -mm | -ms] file ...
deroff [-i | -l] [-kpuw] -mm -ml file ...
The deroff command reads the specified files (or standard input by default), removes all nroff requests, macro calls, backslash constructs, eqn constructs (between .EQ and .EN lines and between delimiters), and tbl descriptions, replacing many of them with spaces or blank lines, and writes the remainder of the file to standard output.
FLAGS
-iSuppresses processing of included files (.so and .nx).
-kKeeps blocks of text specified by requests or macros; for example, the .ne request.
-lSuppresses processing of included files whose names begin with /usr/lib (such as macro files in /usr/lib/tmac).
-maInterprets man macros only.
-meInterprets me macros only.
-mlIgnores mm macros and deletes mm list structures. The -mm flag must be specified with this flag.
-mmInterprets ms and mm macros only.
-msInterprets ms macros only.
-pPerforms special paragraph processing.
-uRemoves _\b and \b in underlined and boldfaced words. Automatically sets the -w flag.
-wFormats output into a word list, containing one word per line, with all other characters deleted.
In text, a word is any string that contains at least two letters and is composed of letters, digits, ampersands (&), and apostrophes (’). In a macro call, a word is a string that begins with at least two letters and contains a total of at least three letters. Delimiters are any characters other than letters, digits, ampersands, and apostrophes.
Trailing ampersands and apostrophes are removed from words.
DESCRIPTION
The deroff command normally follows chains of included files (.so and .nx nroff requests) and processes those files. If a file was already included, a .so naming it is ignored and a .nx naming it ends execution.
NOTES
The deroff command is not a complete nroff interpreter, so it may not handle complex constructs well. Most errors result in too much rather than too little output.
