Quicky: searching for files in directory hierarchy
 

I'm trying to enable 3D support for my radeon PCI video card. In order to do so, I need to find these files:

- "programs/Xserver/hw/xfree86/drivers/ati/radeon_dri.c"
- "programs/Xserver/hw/xfree86/os-support/shared/drm/kernel/radeon _cp.c"
- "programs/Xserver/hw/xfree86/os-support/shared/drm/kernel/radeo n_cp.c"

How would I search for these files from the terminal, or does anyone know where they're located?

find / -name radeo*

That would search for anything starting out with radeo.

man find for more details.
