====== Update all Jenkins plugins at once ======
First make sure you [[https://www.jenkins.io/doc/book/managing/cli/|enabled the jenkins cli]]. In short
go to //JENKINS_URL/me/configure// add the ssh public key and then expose the ssh server port in //JENKINS_URL/configureSecurity///

If you are using the user called dev and you set a fixed port to 44556, execute this:

<code>
UPDATE_LIST=$(ssh dev@localhost -p 44556 list-plugins | grep -e ')$' | awk '{ print $1 }')
if [ ! -z "${UPDATE_LIST}" ]; then 
  echo Updating Jenkins Plugins: ${UPDATE_LIST}; 
  ssh dev@localhost -p 44556 install-plugin ${UPDATE_LIST};
  ssh dev@localhost -p 44556 safe-restart;
fi

</code>
