以前见到的都是替换的，这个怎么是用的竖线呀？
希望有朋友可以解答下。

The syntax of the `s' (as in substitute) command is `s/REGEXP/REPLACEMENT/FLAGS'.
The `/' characters may be uniformly replaced by any other single character within any given `s' command.
The `/' character (or whatever other character is used in its stead) can appear in the REGEXP or REPLACEMENT only if it is preceded by a `\' character.

除了/之外，@或者#等等字符都行。
