awk
programs/scripts, actions preceded by BEGIN
, a predicate (test-action), or END
should insert a space before the opening curly brace ({
). Single-line actions should insert a space after the opening curly and before the ending curly. Functions should insert a newline before/after the opening/closing curly brace. If the function can be written on a single-line in less than 80 characters, space can be used instead of newline.
