DEROFF(1) BSD General Commands 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 nroff(1) and troff(1)
command lines, backslash constructions, macro definitions, eqn(1) con‐
structs (between “.EQ” and “.EN” lines or between delimiters), pic(1)
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(7) macros.
l remove list constructs.
m recognize mm(7) macros.
s recognize ms(7) 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 ALSOeqn(1), nroff(1), pic(1), tbl(1), troff(1)HISTORYderoff appeared in Version 7 AT&T UNIX.
BUGSderoff is not a complete troff(1) 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.
