Such great for everyone ...

I don't know about Linux but I just love N900.
I did flasher 3.5 two times with step by step and it's ok.

But to increase font size I'm 0.
I type: cd/usr/share/themes
it shows: /bin/sh: cd/usr/share/themes: not found

I type: ls *.css
it shows: MyDocs
/home/usere # cd marina/gtk-2.0
/bin/sh: cd: can't cd to marina/

I type: leafpad gtkrc
it shows: leafpad in gtkrc but an empty page only.
I don't what to do next.
I don't find "font definitions"
I don't find "new fonts fremantle"

Please help.
