Unix in a Nutshell, Third Edition, is divided into five parts:
Part I (Chapters 1 through 5) describes the syntax and options for Unix commands and for the Bourne, Korn, and C shells.
Part II (Chapters 6 through 11) presents various editing tools and describes their command sets (alphabetically and by group). Part II begins with a review of pattern matching, including examples geared toward specific editors.
Part III (Chapters 12 through 17) describes the nroff and troff text formatting programs, related macro packages, and the preprocessors tbl, eqn, pic, and refer.
Part IV (Chapters 18 through 20) summarizes the Unix utilities for software development -- SCCS, RCS, and make.
Part V (Appendixes A and B, Bibliography) contains a table of ASCII characters and equivalent values (Appendix A), obsolete commands that are still part of SVR4 and/or Solaris (Appendix B), and a bibliography of Unix books.
