ignorecase in AWK

Question

The following command is working as expected.

# some command | awk '/(<^create>|<^alter>|<^drop>)/,/;/' 
create table todel1 (id int) max_rows=2
/*!*/;
alter table todel1 engine=InnoDB
/*!*/;
create database common
/*!*/;
create database rules
/*!*/;

But it matches only the lower case "create", "alter" etc. I want to use IGNORECASE switch in the awk statement so that it will return all instances of the search term.

Answer 1

Add IGNORECASE = 1; to the beginning of your awk command like so:

bash-3.2$ echo "Create" | awk '/^create/;'
bash-3.2$ echo "Create" | awk 'IGNORECASE = 1;/^create/;'
Create
