Finding the shortest match

[Schwager]

Hi!
I would like to replace

a1 {
someting
}

in the text

a1 {
someting
}
a2{
someting
}
a3 {
someting
}


The expression "a1.*\}\r\n" does find all until the last }
How can I get the shortest match?
Thanks

You could try this:-

a1.*?\}\r\n

The question mark makes the .* less greedy.

That's it!
Thank you!
