sed 命令中的 / 可以用任意字符替换 特别地当处理网址相关问题时

官方说明:

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.

如:

sed -E 's#(http.*github[^/]*/)#https://github.crazypeace.workers.dev/\1#g'

sed -E 's/(http.*github[^/]*\/)/https:\/\/github.crazypeace.workers.dev\/\1/g'

等同。
