Using S3cmd, how do I get the first and last file in a folder?

阅读更多关于 Using S3cmd, how do I get the first and last file in a folder?

问题 I'm doing some processing on Hive. Usually, the result of this process is a folder (on S3), with multiple files (named with some random letters and numbers, in order) that I can just 'cat' together. But for reports, I only need the first and the last file in the folder. Now, if the files number in the hundreds, I can simply download it via the web-gui. But if it's in the thousands, scrolling down is a pain. Not to mention, Amazon loads things on the fly when needed, as opposed to showing it

I am trying to get the files that were uploaded yesterday. what would the command be? 回答1: There is no single command that will allow you to do that. You have to write a script some thing like this. Or use a SDK that allows you to do this. Below script is a sample script that will get

阅读更多关于什么？OSS存储你还在用FastDFS？MinIO了解一下！！！

什么是MinIO ？根据官方定义： MinIO 是在 Apache License v2.0 下发布的对象存储服务器。它与 Amazon S3 云存储服务兼容。它最适合存储非结构化数据，如照片，视频，日志文件，备份和容器/ VM 映像。对象的大小可以从几 KB 到最大 5TB。 MinIO 服务器足够轻，可以与应用程序堆栈捆绑在一起，类似于 NodeJS，Redis 和 MySQL。一种高性能的分布式对象存储服务器，用于大型数据基础设施。它是机器学习和其他大数据工作负载下 Hadoop HDFS 的理想 s3 兼容替代品。为什么需要MinIO？ Minio 有良好的存储机制 Minio 有很好纠删码的算法与擦除编码算法拥有RS code 编码数据恢复原理公司做强做大时，数据的拥有重要性，对数据治理与大数据分析做准备。搭建自己的一套文件系统服务,对文件数据进行安全保护。拥有自己的平台，不限于其他方限制。 MinIO 和其他OSS存储解决方案各有什么优缺点？这里主要针对Ceph、Minio、FastDFS 热门的存储解决方案进行比较。 Ceph 优点成熟红帽继子，ceph创始人已经加入红帽国内有所谓的ceph中国社区，私人机构，不活跃，文档有滞后，而且没有更新的迹象。从git上提交者来看，中国有几家公司的程序员在提交代码，星辰天合，easystack,

logwatch是一款用 Perl 语言编写的开源日志解析分析器。它能对原始的日志文件进行解析并转换成结构化格式的文档，也能根据您的使用情况和需求来定制报告。logwatch 的主要目的是生成更易于使用的日志摘要，并不是用来对日志进行实时的处理和监控的。正因为如此，logwatch 通常被设定好时间和频率的自动定时任务来调度运行或者是有需要日志处理的时候从命令行里手动运行。一旦日志报告生成，logwatch 可以通过电子邮件把这报告发送给您，您可以把它保存成文件或者直接显示在屏幕上。安装: yum install logwatch -y 配置文件：/usr/share/logwatch/default.conf/logwatch.conf 我目前不想让它每天都执行，所以就删掉了/etc/cron.daily/0logwatch文件手动执行 logwatch ################### Logwatch 7.4.0 (03/01/11) #################### Processing Initiated: Wed Apr 29 18:18:37 2020 Date Range Processed: yesterday ( 2020-Apr-28 ) Period is day.

In order to load files larger than 5GB (or even files
