Linux用7zip解压缩分卷文件

Linux⽤7zip解压缩分卷⽂件
背景：在服务器迁移过程中，有⼤量⾮结构化⽂件（主要是office⽂档和图⽚），⽬录结构太⼤，⾼达80-100G，传输耗时且容易受⽹络
等其他原因意外中断，以致于传输失败，于是采⽤分卷压缩，即使传输失败也不会导致全部进度失败，逐个⽂件回传，再逐个上传到服务器。

环境:ubuntu 16.04.3 x64
预安装
apt install p7zip-full
7zip压缩：将data.txt压缩成data.7z
7z a data.7z data.txt\
7zip解压缩：解压data.7z
7z e data.7z 不保持⽬录结构
7z x data2.7z 保持⽬录结构
