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 nonoption arguments.
It then proceeds to cover how gawk
searches for source files,
reading standard input along with other files, gawk
’s
environment variables, 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.
