1、添加依赖

<!--linux连接shell依赖-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>5.7.21</version>
        </dependency>
        <!-- jsch的方式 远程连接的包-->
        <dependency>
            <groupId>com.jcraft</groupId>
            <artifactId>jsch</artifactId>
            <version>0.1.55</version>
        </dependency>

            instance.init("172.161.28.51", 22, "root","root");


        //项目清除 1、clean 2、分析


//            ls = instance.execCmdErrContent("cat /opt/dmdbms/log/dm_DW1_01B_202203.log | grep -v 'INFO'");
//            String ls = instance.execCmd("cd /root/scan/pro;ls");
//            String ls2 = instance.execCmd("cd /root/scan/pro");

//            String ls = instance.execCmd("top -p 21475 -n 1 -b");
            ls = instance.execCmd("ls");


            if (!ObjectUtils.isEmpty(ls)) {
                throw new RuntimeException();
            }

        } catch (Exception e) {
           e.printStackTrace();
        }


        //返回的结果遍历
            List<String> lineFreedList = StrSplitter.splitByRegex(StrUtil.trimToEmpty(ls), "\n", -1, true, true);
            for (String s : lineFreedList) {
                List<String> stringList = StrSplitter.split(StrUtil.trimToEmpty(s), "=", -1, true, true);
                System.out.println(stringList);

            }



        return ;

    }
