BashScript to disable non performing Jenkins Plugin (Cure Slowness- Make Jenkins Fast Again)

 

 Here’s a portable bash script to disable the nonessential plugins we turned off (mercurial, theme-manager, dark-theme, pipeline-graph-view) on any Jenkins host:

#!/usr/bin/env bash

  set -euo pipefail

  JENKINS_HOME="${JENKINS_HOME:-/var/lib/jenkins}"

  PLUGINS_DIR="${JENKINS_HOME}/plugins"

  PLUGINS=("mercurial" "theme-manager" "dark-theme" "pipeline-graph-view")

  echo "JENKINS_HOME: $JENKINS_HOME"

  echo "Disabling: ${PLUGINS[*]}"

  for p in "${PLUGINS[@]}"; do

    for ext in jpi hpi; do

      if [[ -f "${PLUGINS_DIR}/${p}.${ext}" ]]; then

        sudo touch "${PLUGINS_DIR}/${p}.${ext}.disabled"

        echo " - ${p}.${ext} -> disabled"

      fi

    done

  done

  echo "Restarting Jenkins..."

  sudo systemctl restart jenkins

  echo "Done. Check status with: sudo systemctl status jenkins"

 Save/run it on the Jenkins controller (or any similar instance) with sudo rights. It only creates .disabled markers for the listed plugins if present, then restarts Jenkins
