how to regular expression match benchmark's name if the name has "$" in it

[Bo Zhang]

Hi there,

I am using JMH to run benchmarks. I accidentally find a benchmark 
method, whose name is "findAllIn$chars$100$1k".

In this case, how can I use regex to match this name in my "java -jar 
./test/benchmark.jar  <regex match>" command?

Thanks,
Bo
