it appears the next instruction you give is "file linux". i get an error returned : "linux: can't stat 'linux' (No such file or directory)."
i moved on from there and tried your next command : "rm linux". in this case i get the following error message: "rm: cannotremove 'linux' : No such file or directory"
is there supposed to be a "linux" directory in /usr/src/ ?
i don't want to miss anything here; what am i doing wrong?
as you can see in the directory listing you don't have anything in there, so thats why you couldn't use the "file" command nor the "rm" command cause nothing is there to run them on ...
so no your not doing anything wrong, all that that meant is that you didn't have your kernel source install for whatever kernel your currently running ...
so you should have just skipped to the step that states :
tar -zxvf linux-x.x.x.tar.gz
**"unpack the tarball (new kernel)"**
to untar the new kernel and start the process ;-)
