sed

What is the usage of sed in UNIX operating system. Is this used in any application programming or where it is used?

[B]sed[/B] is a stream editor. According to me, the best stream editor present there. You can do wonderful things with sed as it is tremendeously powerful. It is mainly used with unix scripting.

I have already posted a link about sed in another thread in the same forum. For your benifit I'll post it here.
