func RunAwk ¶

func RunAwk(w io.Writer, r io.Reader, args []string, opts AwkOptions) error

RunAwk executes a basic AWK-like pattern scanning This is a simplified subset supporting: - Field access ($1, $2, etc.) - Print statements - Pattern matching (BEGIN, END, /regex/) - Basic string operations r is the default input reader (used when args is empty or contains "-")
