我将网络用于有关定期表达和使用的信息。 我也打开了手套。 然而,我在此提出这个问题,因为我相信有人会利用这两个人,在我拟定解决办法之前,他们也许能够回答这个问题。

是否考虑到一种模式?

引证:
sed s/^(.*)#.*$/1/
或者,这种更好的指挥:
sed s/#.*$//
这里有一只 s子,在指挥线上 works。 这并不是说的,但我手上是:
perl -i -pe s/#main// *.html
否则,你可以使用:
perl -pi.bak -e s/#main// *.html
假设“核心”足够具体,可以简单找到并替代:
find . -name *.html -print0 | xargs -0 sed -i s/#main//g
