gawk: Invoking Gawk
2 Running 'awk' and 'gawk'
**************************
This major node 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 Info file; feel free to skip over things in this
major node that don't interest you right now.
