jenkins清理jobs中不存在的workspace，可能job已被删除，workspace还在占用存储空间

#!/bin/bash
## jenkins-workspace-clean-by-jobs.sh
## 循环寻找jobs任务文件夹
for file in /var/lib/jenkins/workspace/*
do
        if [ -d "$file" ]; then
                job_name=`basename $file`
                if [[ ! -d "/var/lib/jenkins/jobs/$job_name" ]] && [[ ! $job_name =~ '@tmp'  ]]; then
                        echo "$job_name jobs下不存在workspace的这个任务文件夹,可以批量清理掉"
                        rm -rf $file
                fi
        fi
done

# jobs文件夹有多少个任务
workspace_count=`ls -l /var/lib/jenkins/workspace | grep "^d" | wc -l`
echo "workspace文件夹有 $workspace_count 个任务文件夹"


jobs_count=`ls -l /var/lib/jenkins/jobs | grep "^d" | wc -l`
echo "jobs文件夹有 $jobs_count 个任务文件夹"
