DEROFF(1)DEROFF(1)
NAME
deroff – remove formatting requests
SYNOPSIS
deroff
[
option ...
]
file ...
DESCRIPTION
Deroff
reads each file in sequence
and removes all
nroff
and
troff(1)
requests and non-text arguments, backslash constructions,
and constructs of preprocessors such as
eqn(1),
pic(1),
and
tbl(1).
Remaining text is written on the standard output.
Deroff
follows files included by
.so
and
.nx
commands;
if a file has already been included, a
.so
for that file is ignored and a
.nx
terminates execution.
If no input file is given,
deroff
reads from standard input.
The options are
-w
Output a word list, one ‘word’ (string of letters, digits, and
properly embedded ampersands and apostrophes,
beginning with a letter) per line.
Other characters are skipped.
Otherwise, the output follows the original, with the deletions mentioned above.
-_
Like
-w,
but consider underscores to be alphanumeric rather than punctuation.
-i
Ignore
.so
and
.nx
requests.
-ms
-mm
Remove titles, attachments, etc., as well as ordinary
troff
constructs, from
ms(6)
or
mm
documents.
-ml
Same as
-mm,
but remove lists as well.

BUGS
This filter is not a complete interpreter of
troff .
For example, macro definitions containing
\$
cause chaos in
deroff
when the popular
$$
delimiters for
eqn
are in effect.
Text inside macros is emitted at place of
definition, not place of call.
