Description
According official documentation about userparameters
To use positional references unaltered, specify a double dollar sign - for example, awk '{print $$2}'. In this case $$2 will actually turn into $2 when executing the command.
in agent v1 it works as documented, but in the agent v2 it doesn't work
userparemeter looks like:
UserParameter=redis_v1.status[*], redis-cli -h 127.0.0.1 -p 6379 info | grep -v _human | awk -F: '/$1/\{print $$2}'
snippet from debug log:
2020/11/11 15:37:07.099587 [1] created direct exporter task for plugin 'UserParameter' itemid:0 key 'redis_v1.status[evicted_keys]'

2020/11/11 15:37:07.103832 executed direct exporter task for key 'redis_v1.status[evicted_keys]'
p.s. I know about built-in redis plugin in agent v2, this is only example for issue.
