How to read from a dynamic file in Groovy

Question

I've got the log file for a program; the log records every task done by the software. I've modified the software to insert a line such as "operations terminated" into the log when the software is done executing. I am trying to write a script in Groovy that looks for this "operations terminated" line in the log file. I am unsure how to proceed because the log file changes with time and I want to catch "operations terminated" as soon as it pops up. I don't know how to put in a recursive or continuous check... Suggestions? Thanks!

Here is a Q/A on tailing a file in Groovy. Checking the lines for a specific pattern is an easy extension: http://stackoverflow.com/questions/7905605/tail-a-file-in-groovy — Michael Easter, Dec 20 '11 at 23:57

monitoring may be a solution

So then. you could take the delta of the file and search for a specific line/word
