## Scope of This Book

The quick ref is divided into five parts:

- Part I (Sections 1 through 5) describes the syntax and options for UNIX commands and for the Bourne, Korn, and C shells.

- Part II (Sections 6 through 11) presents various editing tools and describes their command set (alphabetically and by group). Part II begins with a review of pattern matching, including examples geared toward specific editors.

- Part III (Sections 12 through 16) describes the nroff/troff text formatting programs, related macro packages, and the preprocessors tbl, eqn, and pic.

- Part IV (Sections 17 through 20) summarizes the UNIX utilities for software development - SCCS, RCS, make, and program debuggers sdb and dbx.

- Part V contains two loose ends: a table of ASCII characters and equivalent values, and a command index to help you locate the commands presented in this book.
