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,
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.
