This manual page describes the GNU version of troff. It is part of the groff document formatting system. It is functionally compatible with UNIX troff, but has many extensions, see groff_diff(7). Usually it should be invoked using the groff(1) command which will also run preprocessors and postprocessors in the appropriate order and with the appropriate options.
It is possible to have whitespace between a command line option and its parameter.
The warnings that can be given by troff are divided into the following categories. The name associated with each warning is used by the -w and -W options; the number is used by the warn request, and by the .warn register; it is always a power of 2 to allow bitwise composition.
There are also names that can be used to refer to groups of warnings:
Note that troffrc and troffrc-end are neither searched in the current nor in the home directory by default for security reasons (even if the -U option is given). Use the -M command line option or the GROFF_TMAC_PATH environment variable to add these directories to the search path if necessary.
The groff info file, cf. info(1), presents all groff documentation within a single document.
