If you are using Jenkins in automation for development process, you may face the pain of updating plugins specially when you have to update more than +20 plugin, as if you navigated to update page you won’t find select all or Install all by single click.

Jenkins is a free and open source automation server. It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery. It is a server-based system that runs in servlet containers such as Apache Tomcat.

So, a trick came to my mind to save more time is by executing a JS code in browser console to select all check boxes by the following steps

Right click on page > inspect > select Console tab

Past the this code in console then press enter to execute.

(function() {
    var aa= document.getElementsByTagName("input");
    for (var i =0; i < aa.length; i++){
        if (aa[i].type == 'checkbox')
            aa[i].checked = true;
    }
 })()

Also while searching I found another why to update all plugins by command line using Jenkins CLI by the following script.

curl -O http://localhost:8080/jnlpJars/jenkins-cli.jar

UPDATE_LIST=$( java -jar jenkins-cli.jar -s http://localhost:8080/ list-plugins | grep -e ')$' | awk '{ print $1 }' ); 

if [ ! -z "${UPDATE_LIST}" ]; then 
    echo Updating Jenkins Plugins: ${UPDATE_LIST}; 
    java -jar jenkins-cli.jar -s http://localhost:8080/ install-plugin ${UPDATE_LIST} --username  --password ;
fi
