我的场景中有 2 个 rar 文件，它们的名称分别是1.rar和2.rar。我的目的：1.rar提取到folder1并2.rar提取到folder2.
首先，我将1.rar文件提取到folder1带有unar( unar -o folder1 x/1.rar) 的文件夹。
一切都很好，但如果我将2.rar文件解压到folder2( unar -o folder2 x/2.rar)，然后将 1.rar 的数据解压到文件夹 2 中。
为什么它要处理以前的 rar 文件？
操作系统：Centos 7。
场景代码：
[root@vm-app home]# unar -o folder1 x/1.rar
x/1.rar: RAR 5
