This chapter covers how to run
awk, both POSIX-standard
gawk-specific command-line options, and what
gawk do with nonoption arguments.
It then proceeds to cover how
gawk searches for source files,
reading standard input along with other files,
gawk’s exit status, using include files,
and obsolete and undocumented options and/or features.
Many of the options and features described here are discussed in more detail later in the Web page; feel free to skip over things in this chapter that don’t interest you right now.
