Selfextracting archive
 

I've got nvidia selfextracting installation. When I run
sh filename.run it decompresses itself into /tmp dir and runs install.
Problem is I need to edit text file 'Makefile' and THEN run the installer.

How can I extract the files without running installation program ? WHat command, I mean ?

And after editing does anyone know how to start installation ? (in my tmp dir I tried typing "nvidia-installer" but it said something like bad command or so... (syntax ? - exec nvidia-installer or ? )

I suggest you follow the way told in nvidia's readme (which, heh, is in the archive ;) I guess it's in their webpage also..), and use

sh filename.run --help

which fills your screen with help on how to work on with the thing.. :) that should get you going.
