Using grep with unsaved buffers.

Using grep with unsaved buffers.

[mopi]

I frequently use buffers that doesn't have a file assiociated to it.

Is it possible to make grep work on those buffers? Perhaps through
stdin? Other alternatives?

M-x occur

In Emacs 22, also M-x multi-occur.

C-x h  C-u M-| grep -e 'regexp' RET

Or

C-x h      M-| grep -e 'regexp' RET

if you want the result in a new buffer.
