AWK tutorial: awk workflow
April 8, 2019
AWK follows a simple workflow − Read, Execute, and Repeat.
BODY block
This block is the core of the awk command. It consists of three parts.
- Read
AWK reads a line from the input stream (file, pipe, or stdin) and stores it in memory.
- Execute
All awk commands are applied sequentially on the input. By default, AWK executes commands for each line entered. However, we can restrict it to a specified pattern.
- Repeat
This process repeats until the file reaches its end.
