DEROFF(1) OpenBSD Reference Manual DEROFF(1)NAMEderoff - remove nroff/troff, eqn, pic and tbl constructs
SYNOPSISderoff [-ikpw] [-m a | e | l | m | s] [file ...]
DESCRIPTIONderoff reads each file in sequence and removes all roff command lines,
backslash constructions, macro definitions, eqn constructs (between
``.EQ'' and ``.EN'' lines or between delimiters), pic pictures, and table
descriptions and writes the remainder to 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.
The options are as follows:
-i Ignore ``.so'' and ``.nx'' commands.
-k Keep blocks of text intact. This is the default behavior unless
the -m option is given.
-m Enable support for common macro packages. The -m option takes
the following arguments:
a recognize man(7) macros.
e recognize me macros.
l remove list constructs.
m recognize mm macros.
s recognize ms macros.
-p Preserve paragraph macros. This option only has an effect if the
-m option is also specified.
-w Output a word list, one `word' (string of letters, digits, and
apostrophes, beginning with a letter; apostrophes are removed)
per line, and all other characters ignored. Normally, the output
follows the original, with the deletions mentioned above.
SEE ALSOman(7)HISTORYderoff appeared in Version 7 AT&T UNIX.
BUGSderoff 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.
The -ml option does not correctly handle nested lists.
