7.1.1 Regular Expressions as Patterns
Regular expressions are one of the first kinds of patterns presented
in this book.
This kind of pattern is simply a regexp constant in the pattern part of
a rule. Its meaning is ‘$0 ~ /pattern/
’.
The pattern matches when the input record matches the regexp.
For example:
/foo|bar|baz/ { buzzwords++ } END { print buzzwords, "buzzwords seen" }
