What is the regular expression to extract the numbers in my sample?

[JoshuaJohn]

I am trying to get the 432233 extracted into a field called memory

memorythread = "432233 KB";

tried ?(/d)

Try this.. It will create a field called memorythread

... | rex memorythread\s=\s"(?<memorythread>\d+)

| rex "memorythread = \"(?<memory>\d+)"
