To be clear, the expression before each code block isn't limited to regular expressions - it can be anything resulting in a boolean value. For instance: <pre lang="C" line="1"># count comment-only lines in a file /^[ \t]*#/{ count++ } (count % 10) == 0 { print count, "comment lines" } END{ print count, "total comment lines" }</pre> Great to see awk being promoted!

To be clear, the expression before each code block isn’t limited to regular
expressions - it can be anything resulting in a boolean value. For
instance:

1
2
3
4

# count comment-only lines in a file
/^[ \t]*#/{ count++ }
(count % 10) == 0 { print count, "comment lines" }
END{ print count, "total comment lines" }
