一.简单说明
在实际的使用场景中，我们可能对压缩过的tar包上传到某个服务器或者应用，会涉及超出服务器限制的文件大小。这里我们可以对此文件进行压缩、分片、合并。
二.实际操作
2.1 压缩包分片
这里，我有个7.5G的tar.gz的压缩包，由于上传的服务器的限制，单次只能上传到700M，这里我们对此文件进行分片：
[root@yuhaohao test]# ls -alh test-1.5.4.1_patch-1.5.2.1_2020-05-15.tar.gz
-rw-r--r-- 1 root root 7.5G May 18 10:24 test-1.5.4.1_patch-1.5.2.1_2020-05-15.tar.gz
[root@yuhaohao test]# split -b 700M test-1.5.4.1_patch-1.5.2.1_2020-05-15.tar.gz test-1.5.4.1_patch-1.5.2.1_2020-05-15.tar.gz. --verbose
