原标题:Regular expression and sed to remove all occurences of some string from hundreds of files

  • sed

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。

I ve got a few hundred html documents with links like the following:
http://www.example.com/subfolder/abc.asp?page=1#main
I need to remove the "#main"

是否考虑到一种模式?

最佳回答

引证:

sed  s/^(.*)#.*$/1/ 

或者,这种更好的指挥:

sed  s/#.*$// 
问题回答

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
