HOSTS: test-host,host2.domain.com, host3.domain.com,another-testing-host,host.domain. com,host.anotherdomain.net,host2.anotherdomain.net, another-local-host, TEST-HOST DATE: August 11 2015 9:00 .......

So I need to extract all the text between the string "HOSTS:" and the string "DATE:", wrap it, and replace the commas

What's the quickest, easiest way to go about doing this? 回答1: You don't need to create an intermediate file.
