troff 命令

常用示例

说明

troff is the typesetting processor of the groff (GNU roff) text formatting system. It reads text files containing formatting commands and produces formatted output for various devices including PostScript, PDF, and terminals. troff is usually invoked through groff, which handles preprocessors (tbl, eqn, pic) and postprocessors automatically. Macro packages provide high-level formatting: man for manual pages, ms for general documents, mom for complex documents. The groff implementation extends traditional Unix troff with color support, additional escape sequences, and improved compatibility features while maintaining backward compatibility.
