Bad handling of double dollar ($$) in user parameters

[dsteinkopf]

Hello,

I already tried a bug report, but is not yet sure if it really is a bug.
See https://support.zabbix.com/browse/ZBX-18568

To be sure that it isn't a problem caused by my installation I began from scratch and did the following steps:

1. use a fresh clean minimal installation of ubuntu 18.04
2. apt-get update ; apt-get upgrade
3. wget https://repo.zabbix.com/zabbix/5.2/u...u18.04_all.deb
4. dpkg -i zabbix-release_5.2-1+ubuntu18.04_all.deb
5. apt install zabbix-agent2
6. vi /etc/zabbix/zabbix_agent2.d/userparameter_diskstats.conf
   • -> enter
     • UserParameter=custom.vfs.dev.read.merged
     • ,awk '{print $$1}' /sys/class/block/$1/stat
7. zabbix_agent2 -t "custom.vfs.dev.read.merged[sda]"
   • -> custom.vfs.dev.read.merged[sda] [s| 6197 3085 672544 4322 1312 1458 636930 2456 0 6860 3260 0 0 0 0]

Is any one able to reproduce this behaviour?
