DEROFF(1) — UNIX Programmer’s Manual
NAME
deroff − remove nroff, troff, tbl and eqn constructs
SYNOPSIS
deroff [ −w ] file ...
DESCRIPTION
Deroff reads each file in sequence and removes all nroff and troff command lines, backslash constructions, macro definitions, eqn constructs (between ‘.EQ’ and ‘.EN’ lines or between delimiters), and table descriptions and writes the remainder on the standard output. Deroff follows chains of included files (‘.so’ and ‘.nx’ commands); if a file has already been included, a ‘.so’ is ignored and a ‘.nx’ terminates execution. If no input file is given, deroff reads from the standard input file.
If the −w flag is given, the output is a word list, consisting of one ‘word’ ( a string of letters, digits, and apostrophes, beginning with a letter; apostrophes are removed) per line, and all other characters ignored. Otherwise, the output follows the original, with the above mentioned deletions.
SEE ALSO
BUGS
Deroff is not a complete troff interpreter, so it can be confused by subtle constructs. Most errors result in too much rather than too little output.
