The book then delves deeper into more complex tasks, such as printing formatted output in AWK, control flow statements, GNU’s implementation of AWK covering the advanced features of GNU AWK, such as network communication, debugging, and inter-process communication in the GAWK programming language which is not easily possible with AWK.
- Master the fastest and most elegant big data munging language
- Implement text processing and pattern matching using the advanced features of AWK and GAWK
- Implement debugging and inter-process communication using GAWK
This format is also useful for running short or medium-sized awk programs from shell scripts, because it avoids the need for a separate file for the awk program. A self-contained shell script is more reliable because there are no other files to misplace
