grep command
 

what does grep do?

I know it's a noobish question but I couldn't fimd the answer anywhere else...


I always see "X | grep Y"
explaination would be awsome... :]
:newbie:

Type man grep at your terminal's window prompt and you will get your answer with details :)

In brief: grep searches streams for patterns; the stream
can be a file or another programs output. It does this in
a line-oriented manner: in other words, each line that
matches pattern will be found(displayed) by default.
