And this " -i" flag, if you go through the man page and look at it, it stands for " interactive" .

这个“-i”标志，如果你浏览一下手册页并查看它，它代表“交互式”。

For some commands the man page is useful but sometimes it can be tricky to decipher because it's more kind of a documentation and a description of all the things the tool can do.

对于某些命令，手册页很有用，但有时解读起来可能很棘手，因为它更像是文档和该工具可以执行的所有操作的描述。
