@micw Could you be convinced to specify a license on this script? Maybe just an MIT or similar? Without some form of license, it would be all rights reserved, and even the many existing forks are strictly speaking in violation of your copyright, probably even if those forks that are unmodified. Also, no one would be allowed to actually use your really nice script or any of the forks out there.

If you need inspiration, I often find https://choosealicense.com/ very useful.

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
