You have installed some plugins and now you need to remove a plugin because it's not required. Removing an ElasticSearch plugin is easy to uninstall if everything goes right, otherwise you need to manually remove it.
This recipe covers both cases.
You need an installed working ElasticSearch server with an installed plugin. Stop the ElasticSearch server in order to safely remove the plugin.
ElasticSearch Plugin Manager, which comes with its script wrapper (plugin), provides command to automatically remove a plugin.
On Linux and MacOSX, call:
plugin -remove mobz/elasticsearch-head
or
plugin -remove head
On Windows, call:
plugin.bat -remove mobz/elasticsearch-head
or
plugin.bat –remove head
