Hi ,

While I'm try to install a package such "license & shield" via command "bin/elasticsearch-plugin install" I'm getting error : **ERROR: Unknown plugin license**

I tried to install the packed as written in your documentation [https://www.elastic.co/guide/en/shield/current/installing-shield.html#deb-rpm-install](https://www.elastic.co/guide/en/shield/current/installing-shield.html#deb-rpm-install) for the installation procedure.

I most mention that I have installed other plugins such "x-pack" with out any problems

here is the command / error in the end of it  
my system is RedHatEnterpriseServer 7.3 x64

/usr/share/elasticsearch $ sudo bin/plugin install license  
A tool for managing installed elasticsearch plugins

## Commands

list - Lists installed elasticsearch plugins  
install - Install a plugin  
remove - removes a plugin from Elasticsearch

Non-option arguments:  
command

Option Description

* * *

-h, --help show help  
-s, --silent show minimal output  
-v, --verbose show verbose output  
**ERROR: Unknown plugin license**

any suggestions what can I do to solve this issue?

Thanks.

If you are using elastic 5.x then you just need to install x-pack
