Replace Title

[neo_philiac]

I want to replace only the titles of a group of pages in certain folder all at once without going thru page by page. Is there a way to do that? Please let me know ASAP. Are there other efficient way to do it.?

sed 's/<title>Old Title<\/title>/<title>New Title</title>/i' /path/to/folder/*.html
