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
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 major node rounds out the discussion of `awk' as a
program and as a language.
While a number of the options and features described here were
discussed in passing earlier in the book, this major node provides the
full details.
