deroff - remove nroff/troff, tbl, and eqn constructs
deroff
[ -m [ m | s | l ] [ -w ] [ -i ] [ filename... ]
SUNWdoc
deroff reads each of the filenames in sequence and removes all troff(1)
requests, macro calls, backslash constructs, eqn(1)
constructs (between
.EQ and
.EN lines, and between delimiters), and tbl(1)
descriptions, perhaps
replacing them with white space (blanks and blank lines), and writes the
remainder of the file on the standard output. deroff follows chains of included
files (.so and .nx troff commands); if a file has already been included,
a .so naming that file is ignored and a .nx naming that file terminates execution.
If no input file is given, deroff reads the standard input.
- -m
- The
-m option may be followed by an m, s, or l. The -mm option causes the macros
to be interpreted so that only running text is output (that is, no text
from macro lines.) The -ml option forces the -mm option and also causes deletion
of lists associated with the mm macros.
- -w
- If the -w option is given, the
output is a word list, one ‘‘word’’ per line, with all other characters deleted.
Otherwise, the output follows the original, with the deletions mentioned
above. In text, a ‘‘word’’ is any string that contains at least two letters
and is composed of letters, digits, ampersands (&), and apostrophes (fm);
in a macro call, however, 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, apostrophes, and ampersands.
Trailing apostrophes and ampersands are removed from ‘‘words.’’
- -i
- The -i option
causes deroff to ignore .so and .nx commands.
eqn(1)
, nroff(1)

tbl(1)
, troff(1)
deroff is not a complete troff interpreter, so it
can be confused by subtle constructs. Most such errors result in too much
rather than too little output.
The -ml option does not handle nested lists
correctly.
