![为什么 SED man -i 选项没有描述?](https://linux22.com/image/1348048/%E4%B8%BA%E4%BB%80%E4%B9%88%20SED%20man%20-i%20%E9%80%89%E9%A1%B9%E6%B2%A1%E6%9C%89%E6%8F%8F%E8%BF%B0%EF%BC%9F.png)
我的 Sed 的 man 输出如下内容:
Zero- or One- address commands
= Print the current line number.
a \
text Append text, which has each embedded newline preceded by a backslash.
i \
text Insert text, which has each embedded newline preceded by a backslash.
q [exit-code]
我一直在试图弄清楚如何进行就地编辑,似乎可以进行切换,-i
但是我之前看不到它,因为我的人没有它的描述,有什么线索可以解释为什么吗?
