Removes nroff/troff, tbl, and eqn constructs.
deroff [ -m [m | s | l ] ] [ -w ] [ -i ] [ filename]
| -m [ m | s | l ] | 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 ('); 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. |
| filename | Name of file to remove constructs. |
* The deroff command 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.
