NOTE: This answer from Ken moved from suggested edit to own answer.
here’s a full command line example using a variant of the above
mysql -u username INFORMATION_SCHEMA
--skip-column-names --batch
-e "select table_name from tables where table_type="VIEW"
and table_schema="database""
| xargs mysqldump -u username database
> views.sql
This extracts all of the view names via a query to the INFORMATION_SCHEMA database, then pipes them to xargs to formulate a mysqldump command. –skip-column-names and –batch are needed to make the output xargs friendly. This command line might get too long if you have a lot of views, in which case you’d want to add some sort of additional filter to the select (e.g. look for all views starting with a given character).
