    Description

      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 15:37:07.099706 executing direct exporter task for key 'redis_v1.status[evicted_keys]'
      2020/11/11 15:37:07.099731 [UserParameter] executing command:' redis-cli -h 127.0.0.1 -p 6379 info | grep -v _human | awk -F: '/evicted_keys/\{print $$2}''
      2020/11/11 15:37:07.103809 [UserParameter] command:' redis-cli -h 127.0.0.1 -p 6379 info | grep -v _human | awk -F: '/evicted_keys/\{print $$2}'' length:14 output:'evicted_keys:0'
      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.
