Running awk and gawk

This chapter covers how to run awk, both POSIX-standard and gawk-specific command-line options, and what awk and gawk do with non-option arguments. It then proceeds to cover how gawk searches for source files, obsolete options and/or features, and known bugs in gawk. This chapter rounds out the discussion of awk as a program and as a language.
