在Ubuntu上查看Jenkins日志有以下幾種方法：
sudo cat /var/log/jenkins/jenkins.log查看全部內容，sudo tail -f /var/log/jenkins/jenkins.log實時查看最新內容，sudo grep "關鍵字" /var/log/jenkins/jenkins.log搜索特定關鍵字，sudo less /var/log/jenkins/jenkins.log或sudo more /var/log/jenkins/jenkins.log分頁查看。還可查看特定構建日志，通過Jenkins CLI，使用java -jar jenkins-cli.jar -s http://your-jenkins-url/ -auth username:password console BuildNumber命令，將BuildNumber替換為實際構建編號。
