Awesome,
is there any script to check plugins that are installed

There are multiple ways to list your Jenkins Plugins:

Way 1: Script console(groovy code):
go to http:<Jenkins_URl>/script
Run below command:

Jenkins.instance.pluginManager.plugins.each{
  plugin ->
    println ("${plugin.getShortName()}")
}

Way 2: Command CLI
Download command-CLI jar from : http://<Jenkins_URL>/jnlpJars/jenkins-cli.jar
Run below command:
java -jar jenkins-cli.jar -s http://<JENKINS_URL>/ list-plugins --username "<Jenkins_USERNAME>" --password "<Jenkins_Password>"

Way 3: Jenkins Python API

import jenkins
import json
server = jenkins.Jenkins('<jenkinsurl>', username='<Jenkins_user>', password='<Jenkins_User_password>')
all_plugins_info=server.get_plugins_info()
for each_plugin in all_plugins_info:
    print each_plugin['shortName']

if you are using a file that contains the name of a plugin on each line you can use this command with the above script
./install_jenkins_plugin.sh $(echo $(cat plugins.txt))

@noroutine

For whoever searches for this, make sure you try jenkins rest api first

	curl -X POST \
		--data "<jenkins><install plugin='${name}@latest' /></jenkins>" \
		--header 'Content-Type: text/xml' \
		http://localhost:8080/pluginManager/installNecessaryPlugins

You should update your example to include the Crumb Issuer Header as well.

Jenkins' docker build has a script for this: https://github.com/jenkinsci/docker/blob/master/install-plugins.sh
