使用sed查找/替换特定文件中的文本

Question

I have a html file that I'm trying to use sed to automatically find a particular line and have this replaced but I am having no joy so far..

<div infinite-scroll='tabs[tabIndex].FeedService.loadFeed(false, tabs[tabIndex].FeedService.filters)'>

I would like to simply grab the entire line and replace to the following line using sed

<div infinite-scroll-labs="tabs[tabIndex].FeedService.loadFeed(false, tabs[tabIndex].FeedService.filters)" infinite-scroll-labs-container="window">

// my attempt..

sed -r --posix "infinite-scroll='tabs[tabIndex].FeedService.loadFeed(false, tabs[tabIndex].FeedService.filters, search.text, search.dateFrom, search.dateTo)' infinite-scroll-disabled='tabs[tabIndex].FeedService.busy || tabs[tabIndex].FeedService.noMoreResults || !tabs[tabIndex].active || tabs[tabIndex].FeedService.initialLoad' infinite-scroll-distance='1' infinite-scroll-immediate-check='false'\\infinite-scroll-labs="tabs[tabIndex].FeedService.loadFeed(false, tabs[tabIndex].FeedService.filters, search.text, search.dateFrom, search.dateTo)" infinite-scroll-labs-container="window" app/feed.html > $cur_dir/www/feed.html

How is the best way to go about this?

如果您确定这是您要更改的确切行，那么也许可以使用：

sed "s#^\(<div infinite-scroll\)='\(tabs\[tabIndex\]\.FeedService\.loadFeed(false, tabs\[tabIndex\]\.FeedService\.filters)\)'>\$#\1-labs=\"\2infinite-scroll-labs-container=\"window\">#"
